To practice calculating the work done by a constant force, follow Tactics Box 10.1.

To find the work done on an object by a force, begin with a visual overview and follow Tactics Box 10.1. Recall that the work \( W \) done by a constant force \(\vec{F}\) at an angle \(\theta\) to the displacement \(\vec{d}\) is given by:

\[ W = Fd \cos \theta \]

The vector magnitudes \( F \) and \( d \) are always positive, so the sign of \( W \) is determined entirely by the angle \(\theta\) between the force and the displacement.

Answer :

The normal force has done no work on the box (Wn).

What is a scientific force?

The term "force" has a precise definition in science. At this level, it makes perfect sense to refer to a force as either a push or a pull. An object does not contain a force or "have it in it.
