explain with suitable example rest and motion
Answers
Answer:
The general study of the relationship between motion, force and energy is known as mechanics. It is subdivided into three parts i.e. kinematics, dynamics and statics. Kinematics deals with the study of the motion of the objects without taking into account the forces and energies that may be involved. The first thing we need to know is that there is no absolute rest or absolute motion. Rest and motion are relative terms.
In simple terms, an object that changes its position is said to be in motion while the opposite action causes an object to be at rest. However, perspective plays a huge role in it. Take the example of an atom which is always in motion but when we see an object in the macro world it seems to be at rest. Therefore, rest and motion both depend mainly on the frame of reference of the one who is observing the scene.
