Question

The work done on an object does not depends on

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

Answer 1

The correct option is C initial velocity of the object.

Work done by any force is the product of the force in the direction of displacement and the magnitude of displacement. The work done depends on the force and displacement.

$(W=\overrightarrow{F}\cdot \overrightarrow{d})$, when force and displacement is perpendicular to each other work done is zero. Hence work done also depends upon the angle between the force and displacement but not on the velocity of the moving object.
