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

Dec 18, 2016

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:

$W = F \times d$

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!
