Starting from rest a scooter acquires a velocity of $36\, km h^{-1}$ in $10 \,s$ and then brakes are applied it takes $20\, s$ to stop. Calculate acceleration and distance travelled.
What conclusion can you draw from the displacement$-$time graph of a body as shown below ?
A particle is moving in a circular path of radius $r$. The displacement after half a circle would be :
Two cars moving in opposite directions cover same distance $'d'$ in one hour. If the cars were moving in north$-$south direction, what will be their displacement in one hour ?
$(a)$ Differentiate between uniform linear and uniform circular motion.
$(b)$ Write any four examples of uniform circular motion.
$(c)$ Is uniform circular motion is accelerated motion ?
