Question

The work done on a body does not depend upon the:

• A. Force applied
• B. Displacement
• C. Initial velocity of the body
• D. Angle at which force is inclined to the displacement

Answer 1

The correct option is C

Initial velocity of the body

1. Work done by any force is the product of the force in the direction of displacement and the magnitude of displacement.
2. $W=F\times d\times \cos \left(\theta \right)$
3. The work done depends on the force and displacement.
4. When force and displacement are perpendicular to each other then the work done is zero.
5. Therefore, work done also depends upon the angle between the force and displacement but not on the velocity of the moving object.

Hence, option C is correct.
