The following displacement $-$ time graph shows the positions of a body at different times, Calculate the velocity of the body as it moves from : $(i) A-B \,(i i) B-C$ $(iii)$ $C-D$.
The following displacement $-$ time graph shows the positions of a body at different times, Calculate the velocity of the body as it moves from : $(i) A-B \,(i i) B-C$ $(iii)$ $C-D$.
Velocity is given by the slope of the graph,
$(i)$ $\quad V _{ AB }=\frac{(3-0)}{(5-2)}=1 m s ^{-1}$
$(ii)$ $\quad V _{ BC }=\frac{(0)}{(7-5)}=0 m s ^{-1}$
$(iii)$ $\quad V_{ CD }=\frac{(0-3)}{(10-7)}=-1 m s ^{-1}$
