IMPORTANT FORMULAS FOR MOTION

There are some few motion formulas that you should know for the test.

1. Distance = speed x time 

2. Work = Force x distance

3. acceleration = change in velocity  =  Final velocity - Initial velocity  

                            change in time              Final time - Initial time

                            

Positive slope means the car is accelerating, that is the velocity is increasing with time. Zero slope means the velocity is constant (that is, not changing with time), and negative slope means the car is slowing down (that is, the velocity is decreasing with time)

Also, you must know the standard international (SI) units of the following:

1. Work -------------Joules (J)

2. Force ------------- Newtons (N)

3. Velocity ---------- meters per second (m/s)

4. Time ------------ seconds
