Answer:
Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.
Work done is defined as product of the force and the distance over which the force is applied. Work is done when a force is applied to an object and the object is moved through a distance. For example, when you lift a load you are applying a force over a distance so you are doing work.
