Draw a velocity-time graph for a body moving with an initial velocity $u$ and uniform acceleration $a$. Use this graph to find the distance travelled by the body in time $t$.

The figure shows the velocity-time graph for two cars A and B moving in the same direction. Which car has the greater acceleration? Give reason to your answer.

The figure shows the displacement-time graph for four bodies A, B, C, and D. In each case state what information you get about the acceleration (zero, positive or negative).

Draw a velocity-time graph for the free fall of a body under gravity, starting from rest $\left(\mathrm{g}=10 \mathrm{m} {\mathrm{s}}^{-2}\right)$.
