"rest and motion are the relative terms". explain with an example of class 9
Answers
Answer:
Rest and motion are the relative terms because they depend on the observer's frame of reference. If an observer is at rest in his or her own frame of reference, but he may be moving in other observer's frame of reference.
Explanation:
There is no such term called absolute motion and all motions are relative. A body is moving with respect to a body at rest but it may be in rest with respect to another moving body with same speed.
Hence rest and motion are relative to each other as motion and rest depends on the observer or frame reference or observation.
Example
If the speed of both cars are different then both cars are in motion with respect to each other.
I can help you in better way if write full question/example which you are talking about.
Circular Motion: Going around in circles, and not attached to the center of axis. Like Planets which go in circular orbits (not all)
Rotary motion: Going around in circles, when attached to the axle, or the center of axis. Like the arms of a watch or clock.
rest and motion are the relative term because they depend on the observers frame of reference.so if two different observers are not at rest with respect to each other,then they too get different results when they observe the motion and rest of a body
