Answer:

B. The object moves some distance

Explanation:

  • Work is the product of force and distance.
  • Work is done on an object when a force is applied on the object making it move some distance.
  • For example; If a mason applies a force of 5 N to move a stone at a distance of 10 m, then the work done will be 50 Joules.
  • Applying a force on an object without making it move some distance then there is no work done.
  • Consider a boy pushing a wall really hard and the wall doesn't move even for a single inch, this means there is no work done.
