Explain the differences between the two graphs.
If the displacement of an object is proportional to square of time, then the object moves with
Derive following equations for a uniformly accelerated motion
$(i)$ $v=u+a t$
$(ii)$ $S=u t+1 / 2 a t^{2}$
$(iii)$ $v^{2}-u^{2}=2 a S,$ where symbols have their usual meaning.
Why does (second)$^{2}$ occur in the unit of acceleration ?
What is the relation between distance and time
$(i)$ when body is moving with uniform velocity ?
$(ii)$ when body is moving with variable velocity ?
