In the given fig., four cases of the speed-time graph are given. In which case is the speed constant? In which case is the speed increasing? In which case is the speed decreasing?  What happens in the fourth case?

The acceleration-time graph for a body is shown in fig.(a). Which of the following figures from fig.(b) would show the velocity-time graph for the same body?

Plot a distance-time graph for uniform speed.

Which of the following graph is possible?

Interpret the regions $\mathrm{a}$, $\mathrm{b}$ and $\mathrm{c}$ in the following graph.

The time of arrival and departure of a train at three stations $\mathrm{A}$, $\mathrm{B}$ and $\mathrm{C}$ and the distance of stations $\mathrm{B}$ and $\mathrm{C}$ from $\mathrm{A}$ are given in the table.

Plot and interpret the distance-time graph for the train assuming that its motion between any two stations is uniform.

Study the velocity-time graph and calculate:

(a) The acceleration from $\mathrm{A}$ to $\mathrm{B}$

(b) The acceleration from $\mathrm{B}$ to $\mathrm{C}$

(c) The distance covered in region $\mathrm{ABE}$

(d) The average velocity from $\mathrm{C}$ to $\mathrm{D}$

(e) The distance covered in region $\mathrm{BCFE}$.
