The displacement $-$ time graph of a body is parallel to time axis. What will you infer about the velocity of the body ?
The body is not moving. Stationary.
A person standing at $A$ goes to $B$ by following any of the paths $1,2$ or $3 .$ Which path we can measure to find the average velocity ?
How can you find the following ?
$(i)$ Velocity from a displacement$-$time graph.
$(ii)$ Acceleration from velocity$-$time graph.
$(iii)$ Displacement from velocity$-$time graph.
$(iv)$ Velocity from acceleration$-$time graph.
Suppose a boy is enjoying a ride on a merry-go-round which is moving with a constant speed of $10\, ms^{-1}$. It implies that the boy is
A body can have zero average velocity but not zero average speed. Justify.
A body is moving along a circular path of radius $R$. Find the displacement of the body when it completes half a revolution.
