Pot 10 interesting acts about chapter 2 and chapter 3. You should have 20 facts total.
ReplyDelete1. About 2000 years ago a Greek philosopher and scientist named Aristotle became one of the first to really go in depth of what motion was. He put motion in two different classes natural motion and violent motion. Natural motion was the nature of the way the object moved not changing from the four elements. VIolent motion is the motion resulting from pushing or pulling. Basically violent motion is the motion caused by another moving force such as a person pushing a cart or the wind moving a ship.
ReplyDelete2. Nicolaus Copernicus was a Polish astronomer who believed that the sun and the moon didn't circle the Earth that the easiest explanation for there general movement was that the Earth moved around the Sun. For many years he didn't publicly discuss his theory on the movement of the Earth and the Sun from fear of being persecuted because the idea of the Earth moving around the sun was very different from common knowledge.
3. Galileo was an Italian born in Pisa; he was the first to create a telescope and then find mountains on the moon and on moons of jupiter. His ideas became very well known because he used a more popularly used language but then he was told by the church to not teach his and Copernican views. He kept his discoveries to himself for fifteen years and then he decided to publish his findings. He was then put on trial and was found guilty so he was forced to renounce his discoveries.
4. Isaac Newton went to school until he was 14 and then his mother took him out of school to work on the farm but he was no help because he would rather read literature he had borrowed instead of working. His mother saw his potential and went to study at a University for five years. During a plague that was going through Europe he went back to his farm house with his mother and then a apple fell on his head and thats when he came up with the theory of gravity. With his theory he was able to figure out centuries old mysteries on the tide of the ocean and planetary movement.
chapter 2
ReplyDelete1) Aristotle believe that every object in the universe had to properly place in their own place or their part of nature; when an object was not proper place in his spot it would of strive to get there.
2) Unlike up and down motion circular motion had no beginning and no end and it would repeat its self without deviation. Aristotle also believe that different rules apply in the heavens.
3) Nicolaus Copernicus believe that all the planets surrounded the sun. He feared that he would get killed if he said anything that contradicted the church so he did not say anything until his lost days of life.
4) galileos experiments was to roll balls in a horizontal plane would neither speed up nor slow down so he finally come to rest not because of it nature but because but friction.
Chapter 2 Facts
ReplyDelete1. Aristotle divided motion into two main classes: natural and violent motion. Natural motion was dependent on the four elements which were earth, water, air, and fire. Violent motion resulted from pushing or pulling forces.
2. Nicolaus Copernicus came up with the theory that the Earth revolved around the Sun. He kept this theory secret because he was afraid of being persecuted by the church for going against their ideas and he doubts about himself.
3. Galileo proved Aristolte's falling body theory hypothesis wrong. He prove Aristotle wrong by doing an experiment where he dropped objects of different weights from the Leaning Tower of Pisa. He found that an object heavier than another object wouldn't fall faster.
4. Newton's first law was the law of inertia which says that an object will continue to do what it is doing unless a force is applied on the object. Newton made this law by improving Galileo's idea of inertia.
5. Newton developed the law of universal gravitation which he used to solve the mysteries of ocean tides and planetary motion. He also invented calculus, and formed the three fundamental laws of motion.
6. A force is a push or pull. It can be caused by gravitational, electrical, magnetic, or muscle source. A group of forces acting on an object is called the net force.
7. The mechanical equilibrium is when the net force on an object is zero. If one force pushes down on something and the other pushes up, they cancel out.
8. The support upward support force
Ten facts about chapter 2
ReplyDelete1. Aristotle believed that different rules apply in the heavens, he said that celestial bodies are perfect spheres made of a perfect and unchanging substance, named quintessence.
2. The cool thing about violent motion was that they moved not of themselves, nor by "nature," but because of pushes or pulls.
3. For many Church leaders, the idea of a moving Earth threatened their authority and the very foundations of faith and civilization.
4. Galileo was the first to provide conclusive refutation through observation and experiment.
5. Galileo argued that, in the absence of friction or other opposing forces, a object moving left or right would continue moving indefinitely.
6. Changes in motion must be imposed against the tendency of an object to retain its state if motion.
7. Isaac Newton was born premature, and barely survived, on Christmas day, and if he had not been born we would know about his first law, the law of inertia.
8. When the net force on something is zero, we say that something is in mechanical equilibrium.
9. The support force and the force of gravity pulling you down have the same magnitude, as when you weigh yourself on a bathroom scale at rest.
10.

ReplyDeleteChapter 2
1) Aristotle was the best philosopher-scientist of his time in greece.
2) Aristotle thought that objects fall at the same speeds proportion to their weight, which means heavier objects fall faster than lighter objects.

1. Aristotle taught the false fact that all motion is due to the nature of it or to the force of push of pull.
ReplyDelete2. Nicolas copernicus theorized that the site of motion from the sun, moon and plants was due to the fact that earth and the planets moved around the sun not the earth.
3. Galileo found that a object twice as heavy as another dropped at the same height and time fell together.
4. Galileo stated that motion always involved a resistive medium such water or air.
5. If there is no interference with a moving object it will not stop.
6.
Chapter 2
ReplyDelete1. Unlike up and motion, circular motion could go on forever, without a begging or and end
2. Motion involved a medium like air and water
3. Galileo tested the hypothesis that id there is no interference with an object that moves, it will keep on going in a straight line forever. (Galileo was trying to prove Aristotle's theory wrong)
4. Each object starts at were it is at rest, and when you push motion against it, it goes in a straight line unless forces ate impressed upon it.
5. Equilibrium are the forces from gravity that are on a lying object.
6. But also, equilibrium could be the constant speed in a straight line path because equilibrium is the state of NO change.
7. when something os pushed horizontally across a floor at a constant speed, it is called dynamic equilibrium.
Chapter 3
1. Everything moves even when you think things are at rest.
2. When things are at constant speed, there is no slowing down or speeding up.
3. Whenever velocity changes, you are changing the speed and the direction on where the object goes.
4. Acceleration is how quickly fast changes.
Ten interesting facts about chapter 2.
ReplyDelete1. catholic religion believed that the earth was in the center of the universe .
2. Nicolaus Copernicus believed that the simplest way to know how the universe worked was to imagine the world and the rest of the planets rotate around the sun.
3. Galileo believed that their was no need for any push, pull, or force of any kind, so that a moving object would stop moving if their was no interference.
4. Galileo would drop objects from the leaning tower to test his theories.
5. Galileo observed in a long smooth surface that the less friction, the more the motion approaches constant speed.
6.
Chapter 2

7. As an object falls it gains speed.
8. Air resistance is responsible for different accelerations with falling objects.
9. It took nearly 2000 years to reach a clear understanding of motion from the time of Aristotle.
10. How high you jump and your speed depends on the the force you put into it, like basketball players jumping for a dunk.
1.Aristotle assserted that natual motion proceeds from the nature of an object dependent on what combination of the four elements (air and fire) the object contains.
ReplyDelete2.The cocept of the violent motion had its difficuties for the pushes and pulls responsible for it kiere not always evident.
3.Newtons first law of motion continues in its state of rest or of uniform motion in a straight line, unless is compelled to charge that state by forces impresse upon it.
4.Equilibrium is a state of no charge it follow from Newtons first law that an object under the influence of only one force cannnot be in equilibrium.
5.Natural motion could be either straight up or straight down as in case of all things on earth of it could be circular as in the case of celestial objects.
6.When there was less friction the motion of objects persisted for a longer time the less the friction the more the motion appoached constant speed.
7.For many church leaders the idea of a moving earth threntened not only their authority but they very foudations of faith and civilization as well.

10.Aristotles views had become so formadably a part of church doctorine to contradic them was to question the church itself.
10 things about chap 3
ReplyDelete1.constant direction is a the straight line objects path doesnt curve.
2.if either the speed or the direction changes or if both change then the velocity changes.
3. we accelerate whenever we move ina curved path even if we are moving at constant speed because our direction is changing hence our velocity is changing.
4.we distinguish speed & velocity for this reason & define acceleration as the rate at which velocity changes thereby encompassing changes both in speed & indirect.
5.which straight line motion is being considered it is common to use speed & velocity interchangeably.
6.things fall because of the force of gravity.
7.it is a common observation that many objects falls with unequal accelerations.
8.things in motion often have variations in speed.
9.average speed can be calculated rather easily.
10.the term acceleration applies to decrease as well as to increase in velocity.
Chapter 2 Facts Continued
ReplyDelete8. The two forces acting on a scale are the gravitation force pulling on you and the support force pushing up from the floor.
9. When a bird drops for a worm it is unaffected by the speed at which the Earth moves. The bird is unaffected because all the objects are moving at the same speed and they remain in motion if there are no forces acting on them.
10. Galileo was sent to trial for his work and the church made him renounce the discoveries he made.
Chapter 3 Facts
1. Galileo was the first to incorporate the distance covered and the time it takes with measuring speed.
2. The average speed is the entire distance traveled divided by the complete time traveled. The average speed is different from the instantaneous speed.
3. Velocity is the speed and the direction of an object. The difference between speed and velocity is that velocity also has the direction.
4. Acceleration is how fast the velocity of something changes. Acceleration can be used to express the decrease and increase in velocity. The decrease in velocity is called deceleration.
5. Speed and velocity are exchangeable when you and talking about straight line motion. With straight-line motion, acceleration can be used to describe the rate at which the speed changes.
6. The person who developed the idea of acceleration by using inclined planes in his experiments was Galileo. He found that a ball rolling downhill gained speed and one going uphill decreased in speed.
7. An object that is in a state of free fall has no restraints except for gravity. It would gain 10 meters per second as it fell.
8. Galileo discovered that the distance an object travels is proportional to the square of time, if the acceleration is consistent.
9. In a vertical leap, jumping force is only applied you touch the ground.
10. Basketball player Spud Webb had a vertical jump of 1.25 meters or roughly 4 feet. He had a hang time of one second.
CHAPTER 2:
ReplyDelete1. Newton refined Galileo’s idea and made it his 1st law. Law of Inertia: every object continues in its state of rest or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it.
2. For many church leaders, the idea of a moving earth threatened not only their authority but the very foundations of faith and civilization as well.
3. Galileo found that a stone twice as heavy as another did not fall twice as fast. Except for the small effect of air resistance, found that objects of various weights, when released at the same time, fell together and hit the ground at the same time.
4. If an object is moving, it continues to move without turning or changing its speed.
5. In the absence of net forces a moving object tends to move along a straight line path indefinitely.
6. Support force is produced by compressed atoms. Ex: book lying on a table. The table compresses atoms which behave as a microscopic springs. The weight of the book squeezes downward on the atoms and they squeeze upward on the book.
7. Earth would have to travel at a speed of 107,000 kilometers per hour to circle around the Sun in one year.
8. Aristotle divided motion into two classes: natural motion and violent motion. Natural motion moves straight up and down or maybe circular in the case of celestial objects. Violent motion resulting from pushing or pulling forces.
9. The results of net force are both the same expressed either in Newton’s or pounds.
10. An example of inertia is flipping a coin in an airplane, because it behaves as if the airplane were at rest.
CHAPTER 3:
1. You’re moving 107,000 kilometers per hour relative to the sun and moving even faster relative to the center of our galaxy.
2. A car traveling at 50 kilometers per hour. It usually goes at that speed for less than one hour. If it did go at that speed for a full hour it would cover half distance 25 kilometers. If it continued only for one minute it would cover less than 1 kilometer.
3. There are three controls that change velocity in an automobile. The gas pedal, the brakes, and the steering wheel.
4. Regardless of the weight or size of an object, Galileo discovered that when air resistance is small enough to be neglected, all objects fall with the same unchanging acceleration.
5. During each second of fall, the object gains a speed of 10 meters per second. It is acceleration. The unit of time, the second enters twice. Once for the unit of speed and gain for the time interval during which the speed changes.
6. Galileo found bigger accelerations for steeper inclines. The ball attains its maximum acceleration when the incline is tipped vertically. Then the acceleration is the same as the falling object.
7. Things fall because of gravity. When a falling object is free of all restraints-no friction, with the air or otherwise-and falls under the influence of gravity alone, the object is in a state of free fall.
8. The physics in basketball are when you leap forward; jumping force is applied only while your feet make contact with the ground.
9. It took people nearly 2000 years from the time of Aristotle to reach a clear understanding of motion.
chapter 2
ReplyDelete1. Aristotle asserted that natural motion proceeds from the nature of an object.
2.Natural motion could be either straight up or straight down, as in the case of all things on earth.
3.Violent motion is resulted from pushing or pulling forces.

7. An object continues to do whatever it happens to be doing unless a force is exerted upon it.
8. If an object is moving, it continues to move without turning or changing its speed.
Chapter 3
1.Motion is relative.
2. Galileo defined speed as the distance covered per unit of time.
3. If we know the speed and the direction of an object then we know its velocity.
4. Constant spped is steady speed.
5. Constant velocity means constant speed and constant direction.
6. In order to change the velocity of something you got to change its speed or direction.
7. Acceleration is when velocity changes quickly.
8. Free fall is when a falling object is free of all restraints.
chapter 1
ReplyDelete1. Aristotle divide motion into two main types: natural motion and violent motion, these are the background to present-day motions.
2. He though every object in the cosmos will have a proper has a place determine by the type of nature it is, if the object isn’t in the right place it would try to get there
3. Aristotle thought that the rate at which it falls is determined by the weight, but was later proved wrong by Galileo
4. Nicolas Copernicus, a polish astronomer, was the first to think of the idea of the earth moving to account for motions of the sun, moon, and the planets.
5. Galileo proved Aristotle idea about a moving object must be propelled by a steady force, but in the absence of a force an object will still keep moving.
6. Objects will continue to do whatever they want to do unless force is applied. Inertia is the property to resist changes in motions.
7. Tension is a stretching force. This can be seen when you tie a sugar bag to a weight. The sugar bag puts tension on the spring.
8. Objects moving at a constant speed in a straight line can be in equal rime. Equal rime is said to be a state of no change.
9. When there are more than one force acting on something than we must consider net force, which was thought of by Isaac Newton thought of.
10. If you and a friend are pushing on an object in opposite directions with the same force, the net force would be zero. This object will not move.
Chapter 3
1. It may not look like it, but everything even objects in rest move relative to the sun and stars.
2. Before Galleo, people thought things just moved fast or slow. Galileo was the first to measure things in speed he measured using the formula speed= distance divided by time.
3. Velocity is defined as the speed of an object and also the directions it is going towards.
4. Acceleration cab both is applied to an increase in velocity and a decrease.
5. We can feel acceleration in a curved path, even if we are moving the same speed due to the change in direction.
6. Galileo was the first to develop the idea of acceleration he had developed this idea due to his experiments on incline planes.
7. Air resistance is responsible for why some things such as a leaf or a feather fall more slowly to the ground.
8. Objects that are not effect by air resistance in a state of free fall will travel to 10m/s squared.
9. It over 2000s years since Aristotle first made the discovery of motion to completely understand it.
10. Objects will travel faster if their plane is tipped vertically.
Chapter 2
ReplyDelete1) Aristotle tried to clarify motion by classification. He devided motion into two main classes: natural motion and violent motion. Natural motion is dependent on these four elemnts: earth, water, air, and fire. Violent motion led to pushing or pulling forces.
2) Nicolaus Copernicus's theory was that the Earth revolved around the sun. He was afraid that the church would persecute him because he was going agains their ideas, so he kept it a secret.
3) Galileo experimented with Aristolte's falling theory. He proved Aristotle worng by dropping objects from the Leaning Tower of Pisa. His conclusion was that if a object is heavier than another it wouldn't go faster.
4) Isaac Newton made his law of inertia by improving Galileo's idea of inertia. Newton's law claims that an object will continue what it's doing unlesss a force is exerted on it.
5) Newton solved the mysteries of ocean tides and planetary motion by using his law of universal gravitation.
6) Newton inveted calculus, and formed the three funamental laws of motion.
7) The net force is a group of forces action on a object. It can be caused by gravitational magnetic, electrical, or muscle source.
8) When the net force on something is zero, it is in mechanical equilibrium. When a force pushed down on something and another force pushed up, they cancel each other.
9) The equilibrium rule gives people a reasonable way to view all things at rest.
10) Objects that move steady, dont speed up, slow down, or change direction always balance to zero.
Chapter 3
1) Calileo was the first person to measure speed by considering the distance covered and the time it takes.
2) The average speed and instantaneous speed are very different. The average sped is the entire distance traveled divided by the time it took to travel. Instantaneous speed is the speed at any instant.
3) The speed and the direction of an object is called velocity.
4) How fast the velocity of something changes is called acceleration. It can be used to express the decrease and increason of velocity.
5) Deceleration is the decrease in velocity.
6) Galileo experiments helped him develop the concept of acceleration. He used inclined planes because he didnt have the right equipment.
7) A falling object that has not restraints except for gravity is in a state of free fall.
8) Galileo also discovered if the acceleration is consisten, the distance an object travels is proportional to the square.
9) Acceleration is often confused with velocity. Acceleration is the rate of which velocity changes. It is a rate of a rate.
10) It took people 2000 years since the time of Aristotle to rach a good understanding of motion.
Chapter 2
ReplyDelete1. Galileo found that a stone twice as heavy as another did not fall twice as fast. When an object of various weights, when released at the same time fall together and hit the ground at the same time.
2. Every object continues in its state of rest, or at uniform motion in a straight line, unless it is compelled to change that a state by forces impressed upon it.
3. An object moving at constant speed in a straight line path is also a equilibrium. Equilibrium is a state of no change.
4. Aristotle asserted that natural motion proceeds from one "nature" at an object, dependent on what the combination of the four elements: earth, water, air, and fire.
5. Violet motion, results from pushing or pulling forces. Violet motion was imposed motion. A person pushing a car or lifting a heavy weight imposed motion.
6. An object continues to do whatever it happens to be doing unless a force is exerted upon it.
7. A force in the simplest sense, is a push or a pull. Its source may be gravitational, electrical, magnetic or simply muscular force.
8. When more than a single force acts on an object we consider the net force, for example if you and a friend pull in the same direction with the equal force on an object, the forces combine to produce a net force twice as great as your single force.
9. Consider a crate being push horizontally across a factory floor. If it moves at a steady speed in a straight-line path. it is in dynamic equilibrium.
10. Objects always balance to zero when they move steady, don't speed up, slow down, or change direction.
Chapter 3
1. We are moving 107,000 kilometers per hour to the sun as we sit here doing our work.
2. People believed that we just moved fast or slow before Galileo.
3. The speed of an object and the direction it is going towards is called velocity.
4. Acceleration is how velocity decreases and increases.
5. Galileo developed the concept of acceleration by using incline planes.
6. Air resistance causes a leaf or a falling feather fall slowly to the floor.
7. Free fall are objects that are not affected by air resistance and travel to 10m/s squared.
8. It is easy to get "how fast" mixed up with "how far."
9. It took 200 years for people to understand motion since the time of Aristotle.
10. Physics is found everywhere, even basketball. When you leap upward, jumping force is applied, but only when your feet hit the ground.
