Differentiate between distance and displacement.

$A$ body moves with a velocity of $2\, m s^{-1}$ for $5\, s$,then its velocity increases uniformly to $10\, m s^{-1}$ in the next $5\, s$. Thereafter,its velocity begins to decrease at a uniform rate until it comes to rest after $5\, s$.
$(i)$ Plot a velocity-time graph for the motion of the body.
$(ii)$ From the graph,find the total distance covered by the body after $2\, s$ and $12\, s$.

$A$ body is moving with a velocity of $10 \, m s^{-1}$. If the motion is uniform,what will be its velocity after $10 \, s$ (in $, m s^{-1}$)?

$A$ motor car slows down from $72 \ km \ h^{-1}$ to $36 \ km \ h^{-1}$ over a distance of $25 \ m$. If the brakes are applied with the same force,calculate $(i)$ total time in which the car comes to rest,and $(ii)$ total distance travelled by it until it comes to rest.

Why is the motion of an athlete moving along a circular path considered an accelerated motion?

The area under a velocity$-$time graph is equal to the
