Question

a man walking on road is said to be in motion why

Answer 1

motion means the movement of any object with respect to time
so if a man is walking on the road then he is moving ahead that's why he is said to be in motion
on this case he is performing rectilinear motion
HOPE IT HELPS !!!!!!

Answer 2

A man is moving on road.. so he is motion

U r asking y

Here it is

How do we say if a body is in motion or not

With respect to its surroundings,
And
Displacement with time .

So when he moves he changes his position with time and also with respect to earth.

Moreover to the waking man the surroundings seems to be moving behind that means he is moving for sure.

Like for an example

When we r in a train

How do we know whether we r moving or not

When we see out of the window that is the surroundings.

But what happens when your train is at rest and the other one right next to u starts moving

It seems u r also moving

So motion is nothing just displacement or change in position with respect to surrounding or earth with time.


hope it helps
