- Acceleration is.....
- Why is it necessary to wear a seat belt to hold you in place if you are riding in a car that stops suddenly?
- a Distance= 5.0 km
- b If not, you will continue moving forward at the car's original speed.

- e Because it's changing direction.
5 Multiple choice questions
- mass (inertia)
- Velocity (speed)
- speed=distance/time s=d/t
- The speed and direction with which an object moves.
5 True/False questions
When calculating acceleration, to find the change in velocity, you subtract the _____________________________ velocity from the __________________________________ velocity. → Velocity (speed)
In the equation a=(vf-vi)/t, Vf stands for what? → The mass of an object
Inertia varies depending on what? → The mass of an object
What does the slope of the distance-time graph give? → zero acceleration
