Question

5. State the condition when a force is applied on a body, the body moves but work done done by the force is zero.​

Answer 1

Answer:

Work done by the force of gravity on the object is zero. Force of gravity acts in the vertical downward direction and the distance covered the the tiobj of force, the horizontal direction. As there is no displacement in th hence the work done is zero.

Answer 2

Answer:

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 ir this case the work that would be zero as the force acting on it is perpendicular.
