A 45 N girl sits on a 8 N bench. How much work is done on the bench? What is the work?

Answer:

No work is done by the girl because the force applied to the bench does not cause it to move.

Explanation:

The definition of work states that work is done on an object whenever a force is applied to an object, and that object is made to move a distance:

#W = F xx d#

In this situation, the force is applied, but no motion occurs. Hence, no work is done by this force.

Unfortunately, I cannot see the point of the question "What is the work?" because there is none!
