Monday 9-14-09 Speed/Velocity definitions and Problems

Example for problems you need to do today:

2. Solve for Distance
Find the distance a car traveled if it drove for 10 s and was traveling at a speed of 20 m/s.

    find and define how to calculate
    1.) average velocity & speed
    2.) instantaneous velocity
    3.) acceleration
    then post five problems where someone has to calculate
    out of those five
    1. solve for instantaneous velocity
    2. solve for average velocity
    3. solve for time
    4. solve for distance
    5. solve for acceleration
    each equation must have units

    1. To get the average speed you must divide the distance moved by time

    2. To find the instantaneous velocity take the change in velocity and multiply it by time

    1. average velocity is a change in velocity.

    Reynaldo Orozco:
    1:average speedis the total distance divided by the total time. V(T)=DS

    2:intantenious speed
    DT
    3:acceleration is the rate of change of velocity with time. it is a vector with direction and magnitude.

    average speed-path distance divided by time interval.
    equation v=a.t
    instantaneous speed- speed at any instant
    equation v=d/t
    acceleration- rate at which an objects velocity changes with time the change in velocity may be in magnitude (speed) or direction in both
    equation v=d/t

    Average velocity-The overall speed of a time period.
    Formula- V=d/t

    Instantaneous speed-Speed that you were going at a certain time.
    Formula-V=a*t

    Acceleration-a change in velocity or speed. There are three kinds: speeding up, slowing down, and turning.
    Formula-A=D/T

    2.The distance the car traveled was 2 meters

    Definitions and Formulas
    *Average velocity is the amount of distance covered in a time in a time period. Formula: v=d/t
    *Instantaneous velocity is how fast an object is moving at a specific time. Formula : v=a*t
    *Acceleration is any change in speed or velocity. Formula: a=d/t

    TO GET THE AVERAGE SPEED YOU HAVE TO DIVIDE THE DISTANCE BY TIME!.
