You are sitting in a moving train. It appears to you as if the trees outside are moving in the opposite direction. This is what we call relative motion. Sun seems moving from east to west daily. But it is only relative to us as we on the earth are moving from west to east.
Relative motion
Relative motion
Motion is relative to an observer's frame of Reference.
Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
At rest and in motion are relative terms. When we say 'in motion' or 'at rest' we mean relative to something else. If you were travelling in a car for instance, you would be at rest relative to the car but in motion relative to the outside world.
Think of two cars driving down a highway in the same direction. One is going 30m/s, and one is going 50m/s. The faster car is going 20m/s relative to the slower car.We can basically think of relative motion as motion of one object compared to that of another object.
motion is realtive
All motion is relative to yourself, as there is no fixed point anywhere in our universe, as it is all traveling away from the center of the big bang. But if we ever find where the bigbang happened, that would be where all motion is relative to
When its position is changing relative to our position. Note: all motion is relative to something else.
He is in motion relative to me, and he is at rest relative to his friends. There is no 'real' rest or 'real' motion. It's always measured relative to something else.
An object's motion in relation to something else
Comparing one motion to another.
