Question

The work done on an object does not depend upon the

• A. displacement
• B. force applied
• C. angle between force and displacement
• D. initial velocity of the object

Answer 1

The correct option is D

initial velocity of the object

1. We know that work done, $W=Fd\cos \theta$, where $F=forceandd=displacementand\theta isanglebetweenFandd$.
2. So, work done does not depend on the initial velocity of the object.
3. So, work done depends on displacement.
4. Work done also depends on the force applied
5. Work done also depends on the angle between force and displacement

Hence, option D is correct.
