Question

why does an object, seems in motion to one person and stationary to some other person ​

Answer 1

Answer:

Explanation:

Motion is a concept that is dependent completely on Frame Of Reference.Talking about motion without declaring the Frame of motion is irrelevant.

When we simply say that a body is moving or is at rest,we mean that its at rest with respect to the ground.While for some observer in outer space,even the ground (Earth) is moving.

So in the ground frame of reference , a tree might be at rest for you but its moving for the observer in outer space.
