Question

TON
1. What is force? Does it always result in work being done? Explain with
the help of an example.

Answer 1

Answer:

Yes, if force is acting on a body work done can be zero. When an object is at rest and no external force except gravity is acting on it in this case the work that would be zero as the force acting on it is perpendicular.For example, When an object is at rest and no external force except gravity is acting on it in this case the work that would be zero as the force acting on it is perpendicular. Therefore the displacement is zero and if displacement is zero work done would be zero.We know that,The work doneW=fsSuppose that displacement is zero then, W=f×0 W=0The work done is zero.

Answer 2

Explanation:

force is a pull or push

yes it always result in work being done

push a book

sometimes doesn't result in work

push a wall
