VELOCITY AND ACCELERATION

VELOCITY= SPEED IN A GIVEN DIRECTION

eg an rollercoaster that is moving round is changing its motion + direction constantly, so its VELOCITY IS NOT CONSTANT.

- 2 MOVING OBJECTS can have the same speed, but different velocities:

a car travelling north at 30m/s has the SAME SPEED as a car travelling south at  30m/s.

but their VELOCITIES are not the same because…
