$A$ trolley,while going down an inclined plane,has an acceleration of $2 \,m \,s^{-2}$. What will be its velocity (in $cm \,s^{-1}$) $3 \,s$ after the start?

What can you say about the motion of an object if its speed-time graph is a straight line parallel to the time axis?

An athlete completes one round of a circular track of diameter $200\, m$ in $40\, s$. What will be the distance covered and the displacement at the end of $2\, min$ $20\, s$?

Which of the following is true for displacement?

What does the path of an object look like when it is in uniform motion?

The speed-time graph for a car is shown in the figure.
$(a)$ Find how far the car travels in the first $4 \, s$. Shade the area on the graph that represents the distance travelled by the car during this period.
$(b)$ Which part of the graph represents the uniform motion of the car?
