Question

Why work is scalar when both force and displacement are vector?

Answer 1

Answer:

Work is a scalar quantity because it is the dot product of two vectors (Force and displacement). Dot product of two vectors becomes scalar quantity. So, work done has only magnitude but not direction. Work done may be positive, negative or zero.3

Answer 2

Answer:-

Work is a scalar quantity because it is the dot product of two vectors(Force and displacement).Dot product of two vectors becomes scalar quantity. So,work done has only magnitude but not direction.
