MCQ
The work done on an object does not depend upon the:
  • A
    Displacement.
  • B
    Force applied.
  • C
    Angle between force and displacement.
  • ✓
    Initial velocity of the object.
✓

Answer

Correct option: D.
Initial velocity of the object.
$\text{W}=\text{F}\times\text{d}\cos\theta$
Here, $F$ = force applied on the object
$d$ = displacement
$\theta$ = angle between force and displacement
So, the work done on an object does not depend upon the initial velocity of the object.
The correct option is $D$.
