Question

What are the essential condition for work has to be done.

Answer 1

1. A work is said to be done if we applied a force on an object and the object moves to a distance.
2. So work done $W=F.s$
3. Where F is the applied force and s is the displacement in the direction of the force.
4. So for work to be done, there should be an applied force.
5. And there should be displacement in the direction of the force.
6. Hence, applied force and displacement are the essential conditions for work done.
