The displacement $-$ time graph of a body is parallel to time axis. What will you infer about the velocity of the body ?

The nelocitu$-$time graph of a body is as shown. What tupe of motion does the body posses ?

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.

Account for the following

$(a)$ What is the shape of the path of a body when it is in uniform motion ?

$(b)$ Give one example of non$-$uniform motion.

$(c)$ Two cars $A$ and $B$ have their $x-t$ graph as shown in figure. Which has greater velocity ?

$(d)$ What is the quantity which is measured by the area occupied below the velocity$-$time graph ?

$(e)$ A body is moving with a velocity of $10\, m s ^{-1}$. If the motion is uniform, what will be the velocity after $10\, s$ ?

A body moves on three quarters of a circle of radius $r .$ The displacement and distance travelled by it are

Differentiate between distance and displacement.
