A body travels 120 m in 40 s. Calculate its average speed.

Distinguish between speed and velocity, and give one example where the speed is constant but the velocity is changing.

Distinguish between distance and displacement.

What does the slope of a distance-time graph represent, and what does the area under a velocity-time graph represent?

A car moving at 20 m s⁻¹ is brought to rest in 5 s. Find its retardation and the distance it travels in that time.

A body starts from rest and moves with a uniform acceleration of 2 m s⁻² for 5 s. Find its final velocity and the distance travelled.

A body travels with a uniform velocity of 15 m s⁻¹ for 4 s and then accelerates at 2 m s⁻² for a further 3 s. Find the total distance travelled.
