Best Answer

Work is the product of a force and a displacement. Both of those are vectors.

There are two ways to multiply vectors. One of them produces another vector,

the other produces a scalar. The calculation for 'work' uses the scalar product.

The procedure is:

(magnitude of one vector) times (magnitude of the other vector) times (cosine of the angle between them).
