Forces in motion

To change the way an object is moving you need a force.

This force can either:
(a) speed up the object like a sprinter at the start of a race
(b) slow down the object like a van nearing a red traffic signal
(c) change the direction of motion like a car turning a corner



The bigger the force the bigger the change of speed and so the bigger the acceleration.
