A body moves on three quarters of a circle of radius $r .$ The displacement and distance travelled by it are
displacement $=r,$ distance $=3 r$
distance $=2 r,$ displacement $=\frac{3 \pi r}{2}$
displacement $=\sqrt{2} r,$ distance $=\frac{3 \pi r}{2}$
displacement $=0,$ distance $=\frac{3 \pi r}{2}$
A particle accelerates from rest at a constant rate for sometime and attains a constant velocity of $8\, m s ^{-1}$. Afterwards it decelerates with a constant rate and comes to rest. If the total time taken is $4$ second, the distance travelled is
Define distance and displacement. A body covers one complete revolution around a circular park of circumference $176 \,m$ in $4$ minutes. Find the displacement of the body after $6$ minutes.
Out of the three speed$-$time graphs shown below
Identify the graph for the following cases.
$(i)$ A ball thrown vertically upwards and returning to the hand of the thrower ?
$(ii)$ A body decelerating to a constant speed and accelerating.
$(a)$ Define uniform circular motion.
$(b)$ Is the uniform circular motion an accelerated motion? Give reasons for your answer.
A body is moving along a circular path of radius $R$. Find the displacement of the body when it completes half a revolution.
