The acceleration of a moving body can be found from

If the position-time graph of a moving object is a straight line,determine the acceleration and velocity at any point.

What do the slope and the area under the $v-t$ graph represent?

The position $x$ of a particle with respect to time $t$ along the $x$-axis is given by $x = 9t^2 - t^3$,where $x$ is in metres and $t$ is in seconds. What will be the position of this particle when it achieves maximum speed along the $x$-direction?

Two cars $P$ and $Q$ start from a point at the same time in a straight line and their positions are represented by $x_P(t) = at + bt^2$ and $x_Q(t) = ft - t^2$. At what time do the cars have the same velocity?

Draw the $x-t$ graphs which represent positive,negative,and zero velocity.
