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).

Work is a scalar quantity because it only has magnitude and no direction. The amount of work done is determined by the force applied and the distance over which the force is exerted, without considering the direction of the force.
