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

The explanation for the correct option

Option D:

1. Work done is defined as product of force time displacement.
2. $W=Fd\left(\cos \left(\theta \right)\right)$, where
3. $W=$work done, $F=$force , $\theta =$angle between the force vector and the displacement vector, $d=$displacement after applying force
4. Therefore, option D is the only left option, so by the process of elimination option D is correct.

The explanation for the incorrect option

Option (A)

From the above formula, we can say that work done depends on displacement.

Option (B)

From the above formula, we can say that work done depends on the force applied.

Option (C)

From the above formula, we can say that work done depends on the angle between force and displacement.

Hence, option D is the correct option.
