Write true or false for the following statements
A quantity which can be completely specified by magnitude as well as direction is called a scalar quantity.
False
Give an example of an accelerated body, moving with a uniform speed.
The following displacement $-$ time graph shows the positions of a body at different times, Calculate the velocity of the body as it moves from : $(i) A-B \,(i i) B-C$ $(iii)$ $C-D$.
By giving an example, prove that rest and motion are relative terms.
A scooter starts from rest moves in a straight line with a constant acceleration and covers a distance of $64 \,m$ in $4 \,s$
$(i)$ Calculate its acceleration and its final velocity.
$(ii)$ At what time the scooter had covered half the total distance ?
A body is moving along a circular path of radius $R$. Find the displacement of the body when it completes half a revolution.
