Answer 2

Explanation:

Two prerequisites are:

1. If there is no motion or change in position even after the application of force, no work is considered to have been completed. No displacement should exist, hence S should equal 0.
2. When the force applied is perpendicular to the displacement and the angle between the displacement and the applied force is 90 degrees.

For instance,

• Although you may not be applying energy when carrying, holding, and standing your bag but the bag is the contrary. As a result, no job is completed.
• Pushing a wall.
• The work done is "zero" when the object's displacement and the force being applied are perpendicular to one another.
• When a force is applied to an object yet the object remains stationary, there is no work done on the object. Another example of doing nothing is pushing a mountain.
