Question

Define motion and rest

Answer 1

whn there is no movement seen in a body then we can say that the body is in state of rest

Answer 2

Motion :

If the position of an object changes as time passes, it is said to be in motion.

We see different things in motion — people and vehicles moves on road, trains move on railway tracks, aeroplanes, birds fly, etc.

Rest :

If the position of an object does not change as time passes, it is said to be at rest.

We say that, any object does not come in motion until an external force is applied to it.
