Question

work done means in physics

Answer 1

work done means that force is applied to an object and object moved at a distance.

Answer 2

According to physics,
Work is said to be done when a body displaces in the direction of force applied.

W=FS

Generally there are three types of works,
1 - Positive work (when displacement is along the direction of force applied)
2 - Null work (when displacement is perpendicular to the direction of force applied)
3 - Negative work (when displacement is opposite to the direction of force applied)
