What is force ???????
Answers
When we push or pull on a body, we are said to exert a force on it. Forces can also be exerted by inanimate objects. For example, a locomotive exerts a force on a train it is pulling or pushing. Similarly, compressed air in a container exerts a force on the wall of the container.The force may produce motion of the body or may cause the body to deform. Energy may be expended in the process, or the applied force may be balanced by an opposing force so that no energy is expended.The distortion or the displacement that occurs when a body is subjected to a force occurs in accordance with Hooke's and Newton's laws governing the behavior of elastic and non-elastic bodies.
