What is the quantity which is measured by the area occupied below the velocity-time graph?

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

State which of the following situations are possible and give an example for each of these:
$(a)$ An object with a constant acceleration but with zero velocity.
$(b)$ An object moving with an acceleration but with uniform speed.
$(c)$ An object moving in a certain direction with an acceleration in the perpendicular direction.

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 $2\, min$ $20\, s$?

What is the nature of the distance-time graphs for uniform and non-uniform motion of an object?

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