Four cars $A$, $B$, $C$ and $D$ are moving on a levelled road. Their distance versus time graphs are shown in Fig. Choose the correct statement
Draw displacement$-$time graphs for the following situations
$(i)$ When body is stationary.
$(ii)$ When body is moving with uniform velocity.
$(iii)$ When body is moving with variable velocity.
Mention the nature of motion of a body if its displacement$-$time graph is a straight line parallel to time axis.
In which of the following cases of motions, the distance moved and the magnitude of displacement are equal ?
Name the force which is responsible for change in position or state of an object.
