ReplyDeleteToday in physics we learned Newtons First Law, which can be found in Ch. 2 on page 22.
force(F)=any push or pull on an object. If your going to apply force on something, you have to touch it.
-force causes motion (acceleration)
-force can stop motion (acceleration)
-constant velocity (zero acceleration) a=om/s2
you have to have a force in order to have acceleration.
reminder acceleration is a change in velocity
Gravitational force is pulling you down while another force is holding you up. The force that is pulling you down and holding you up must be balanced
balanced(no net forces) F=o
net force is all the forces on an object added together.
If force is equal to zero then you are at a constant velocity.
If the forces are not balanced then there will be acceleration, if the forces are balanced then there is no acceleration.
Units:
newton's (N)
pounds (lb)
Mass (m): amount of matter or stuff in an object.
Bigger objects usually have more mass.
Smaller objects usually have less mass.
Units:
Kilograms (kg)
grams (g)
Inertia-the resistance to change in motion
depends on mass; the more mass, the more inertia
ex: If you run into a car whose going to be easier to move? You, because the car has more inertia
100kg=1xInertia
if you have 200kg it =2xInertia
600kg=6x the Inertia

Newtons 1st Law
ReplyDelete-an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
-Law was originally introduced by Galileo, also known as the law of inertia.
-No force is needed to maintain motion. Instead it is needed to stop motion.

ReplyDeleteOn my website it stated
ReplyDeletenewtons 1st law- a body at rest will remain at rest, unless acted on by a net force.
No force is needed to maintain the motion, but it is needed to stop the motion.
It talks about inertia and types of forces like friction.
It can also called the the law of inertia.

TODAYS ASSIGNMENT WE HAVE TO DEFINE NEWTON'S FIRST LAW WICH IS:A BODY AT REST WILL REMAIN AT REST & A BODY IN MOTION WILL REMAIN IN MOTION AT A CONSTANT VELOCITY (CONSTANT SPEED IN A STRAIGHT LINE) UNLESS IT'S ACTED ON BY A NET,EXTERNAL FORSE!.......
ReplyDeleteDefine Newtons first law
ReplyDeleteIs when a object is left alone it maintains a constant velocity. Know the object is not pushed or pulled upon, its velocity will naturally remain constant. so what that means is that once moving at a steady speed in a straight line it will continue to move at a steady speed and straight line.so the object is standing still with no contact by any force.

ReplyDeletenewtons first law
the law of inertia
an object at rest tends to remain at rest, and an object in motion tends to remain in motion at constant velocity (with the same speed and in the same direction) unless acted upon by an unbalanced force.
an object at rest because the forces acting on it are balanced:not because there are no forces upon it. the downward force (mg) of gravity is balnced by an upward force of the table (-mg)
acceleration id the rate of change in velocity
a change in speed (magnitude)
a change in direction
a change in both magnitude (speed) and direction
the velocity of an object remains unchanged unless acted upon by an unbalnced force
or
an object on will experience acceleration if acted upon by an unbalnced force

newtons fist law- when forces are balance , no acceleration occurs; thous an object continues to move at a constant speed or stay at rest.
The law of inertia- an object at rest tends to remain at rest, and object in motion tends to remain in motion at costan velocity (with the same speed an in the same direction) unless acted upon an unbalced force.

newtons first law: an object at rest tends to remain at rest and an object in motion tends to remain in motion at constant velocity (with the same speed and in the same direction) unless acted upon by an unbalanced force.
ReplyDelete-an object remains at rest because the forces action on it are balanced; not because there are NO forces acting upon it.

this website practically rereads the whole lecture but in pictures.
--newtons first law: three physical laws that form the basis for chemical mechanics
1 in the absence of a net external force, a body is at rest or moves with constant velocity.
2. the eternal force on a body is equal to the mass of that body times acceleration (f=am)
3. whenever a first body exerts a force (f) on a second body, the second body exerts a force (f on the first body)

In this slideshow, I learned that newtons 1st law is known as "law of inertia". Every object is always at rest, unless it is added external force. Objects are always in motion until an external force is added.

When an object is not moving, it is at constant velocity which is 0.

Newton was a physicist in the 17th century.He discovered gravity when apple fell in his head. Newton's first law of motion: when a object in a state of uniform motion remains the same state of motion unless an external force is applied to it. Galileo originally introduced this law. It is also known as the law of inertia. Force is needed to start acceleration. It is also needed to stop motion. Forces also include friction. Newton's second law of motion is when the relationship between an object's mass m, its acceleration a, and the applied force F is F= m times a. Newton's third law of motion says that for every action, there is an equal and opposing reaction. Newton's law of gravity states that every object in the universe exerts gravitational force on every other object in the universe. The grater the mass the bigger the gravitational force.
ReplyDeleteThis website gives many examples for Newton's laws. For example, for Newton's law of gravity it gives you an example of a cannon being fired from a raised ground.
http://library.thinkquest.org/04apr/00533/Text-Only/Newton.swf
From my sources (http://science.discovery.com/interactives/literacy/newton/media/newtonfinal415.swf) I found that an object at rest will never move unless an external source pushes on it, and an object in motion will never stop unless another force stops it.
ReplyDeleteThe fine example given on the site was a apple and a worm with zero motion until you click it and a hand pushes it and thus puts it in motion and only the force of a wall stops the worm from moving any more.
Newton's First Law
ReplyDeletewe learned about Newton;s First Law in First period today.
- when an object is left alone, it maintains a constant velocity.
V=0
Uniform motion ( no friction)
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

ReplyDeleteNewton first states: that if an object is not moving it tends to stay in the same position unless something is acted upon it. The same will be said if the object will be in motion. This is law can also be know as the law of inertia. Force is not needed to maintain an object in motion it is only needed in the beginning, but is needed when to stop the object.
http://library.thinkquest.org/04apr/00533/Text-Only/Newton.swf
The website had used a picture to demonstrate how force was applied and how it wouldn't stop unless something was acted upon it It had also talked about all the other laws, and had given a picture for each of the laws they had talked about. It had used sorta of a slide show type format to organized the website.

ReplyDeleteDefine Newtons 1st Law:
Every object is at rest, unless outside force is added to the object to make it move
Newton's 1st law-
ReplyDeleteForces are balanced, no acceleration occurs; thus an object continues to move at a constant speed or will remain at rest.
An object in motion tends to stay in motion at constant velocity(with the same speed and in the same direction)unless acted upon by an unbalanced force.
An object at remains at rest because the forces acting on it are balanced, not because there is no forces on it at all.
Where i got my info-
http://www.sciencegeek.net/Physics/Presentations/NewtonsLaws/NewtonsLaws.swf
Newton's first law of motion: every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This law was first introduced by Galileo. it can also be known as the law of inertia.
ReplyDeleteon the website i went to they talked about who was newton, they showed a picture, and they also talked about his other laws: Newton's second law, Newton's third law and Newton's law of gravity.

Define Newtons first law (the law of inertia)
ReplyDeletefirst law- when an object is left alone, it maintains a constant velocity. (velocity= o) every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
For example in this website they used a block to illustrate how uniform motion works or in other words how it works with out friction.

ReplyDeleteNewton's First Law:
-"An object at rest tends to remain at rest, and an object in motion tends to remain in motion at constant velocity(with the same speed and in the same direction) unless acted upon by an unbalanced force."
- An object remains at rest because the forces that are acting on the object are balanced.
-An object that's in rest on a table has a negative and positive force; One force is holding the object up and another is pushing it down.
-Newton's First law also known to be "The Law of Inertia"

ReplyDeleteTHE WEBSITE THAT HELP ME DEFINE AND GET SOME EXAMPLES WAS
id.mind.net/~rona/mstm/physics/...newtons/newtonlaws.html
The definiton:
ReplyDeleteNewton's first law
This law states that every object stays in a state of rest or constant motion unless forces is impied on it causing it to change it state.
http://voo9.synthasite.com/resources/~Physics%20with%20Arnold.swf
In this website I learned about Newton's first law through a demonstration of a ball that was motionless. This ball was then pushed and it began rolling. The way the law was represented is that the ball that was in constant motion or a state of rest was no longer in that state because a force (the hand that pushed it) was applied to the ball that caused it to move.
This law can also be know as the law of inertia.
reynaldo orozco:
ReplyDeletenewtons firs law:
acceleration is a change in velocity during a specific time period.
objects also accelerate when ever an unbalanced force is applied to them.
mass refers to the quantity of matter in a object.
all objects made of matter have inertia thais , (newtons firs law) but some objects resist more then others.

ReplyDeleteand says
Newtons First Law
"The Law of Inertia"
an object at rest tends to remain at rest, and an objext in motion tends to remain in motion at constant velocity(with the same speed and in the same direction) unless acted upon by an unbalanced force.
Speed vs. Velocity
Velocity is a vector quantity-it has both magnitude and direction.
-the velocity of an object remains umchanged unless acted upon by an unbalaned force or an object on will experience acceleration if acted upon by an unbalanced force.
solving constant and average speed

The website i went to tell us a little bit about isaac newton and who his law was first introduced by and then it shows a picture describing Newtons first law. Newton was a revolutionary classical physicist in the 17th century. His law was first introduced by Galileo then mastered by his. Newtons law states that every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Newtons first law: A body at rest will remain at rest and a body at a constant velocity (constant speed in a straight line) unless it's acted on by a net, external force.
ReplyDeleteAnother example would be An object in motion continues in motion with the same speed and the same direction unless acted upon by an unbalance force.

ReplyDeleteNEWTON'S FIRST LAW
IS AN OBJECT AT REST REMAINS AT REST AND AN OBJECT IN MOTION REMAINS IN MOTION AT A CONSTANT SPEED AND IN A STRAIGHT LINE UNLESS ACTED ON BY AN UNBALACED FORCE.
ALSO IN THE WEBSITE IT TALKS ABOUT NEWTONS SECOND LAW IT SAYS THAT THE ACCELERATION OF AN OBJECT DEPENDS ON THE MASS OF THE OBJECT AND THE AMOUNT OF FORCE APPLIED. A BALL WITH GREATER MASS REQUIRES MORE FORCE THAN A BALL WITH LESS MASS TO ACHIVE THE SAME ACCELERATION.
NEWTON'S THIRD LAW
FOR EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION FOR INSTANCE WHEN YOU KICK A BALL YOUR FOOT EXERTS AN EQUAL AND OPPOSITE FORCE ON YOUR FOOT.
