Question

The work done on an object does not depends upon the:

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

Answer 1

Answer: (D)

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