Explanation:
Detailed explanation-1: -Work depends upon the force applied and distance covered. If the applied force causes an object to move to a distance, work is said to be done.
Detailed explanation-2: -Work = force X distance or W = Fd. Work is expressed in units called joules (J). One joule is equal to the energy expended (or work done) when a force of one newton is applied to an object, and the object is moved a distance of one meter. So, one J is the same as 1 N • m.
