3-Acceleration is defined at a change in velocity. Velocity is ______      A-Speed and direction      B-The same thing as speed       C-distance/time       D-time/distance 

. A car accelerates from a standstill to 70 m/s in 10 seconds. What is the acceleration?    a-0.7m/s2     b-7m/s2     c-14m/s2     d-none of the above 

Acceleration is defined as the CHANGE in ....................... time of motion to another place.            a- velocity           b-distance              c-speed

initial v = 5 m/s, final v = 0 m/s, time is 20 seconds, what is a (acceleration)                                   a-(0-5)/20         b-(5-0)/20               c-5/20                 d-20/(5-0)

True or False : Acceleration only takes place when things speed up.

4-Determine the motion of the car.      A-at rest      b-speeding up     C-moving at constant speed    D-slowing down

When are you undergoing an acceleration in a car?                  a-speed up     b- slow down     c-make turns     d-All of the above

This body has an acceleration or zero acceleration and why ?

Sometimes a body moves with has zero acceleration.

The change in velocity in on second

The unit of measuring acceleration is .............................

Changes in our speed, direction or both are called _________.    a-gravity       b-changes                c-acceleration
