Question

what is the definition of work

Answer 1

An activity involving mental or physical effort  in order to achieve a result is called as work.

Answer 2

Generally, any mental or physical activity is referred to as work. When we walk or run, the energy in our body is used to do the necessary work. We say that a girl who is studying is working or performing work. But that is mental work. In physics, we deal with physical work. Work has a special meaning in physics.

‘Work is said to be done when a force applied on an object causes displacement of the object.’

the work done by a force acting on an object is the product of the magnitude of the force and the displacement of the object in the direction of the force. Thus, Work = force × displacement
