A cheetah can accelerate from rest at the rate of $4 m s^{-2}$
$(i)$ What will be the velocity attained by it in $10\, s$ ?
$(ii)$ How far will it travel in this duration ?
The displacement of a moving object in a given interval of time is zero. Would the distance travelled by the object also be zero ? Justify you answer.
State the meaning of uniform circular motion.
The distance$-$time graph of a body is parallel to time axis. The body is
There are 5 houses on a street, $A, B, C, D$ and $E$. For all cases, assume that positions to the right are positive.
$(i)$ Draw a frame of reference with house $A$ as the origin and the positions of houses $B, C, D$ and $E$.
$(ii)$ You live in house $C.$ What is your position relative to house $E$ ?
$(iii)$ What are the positions of houses $A$ and $D$, if house $B$ is taken as the reference point ?
