work done is scalar quantity?

Expert Answer:

When we multiply two numbers, all we get is another number. But vector quantities can be multiplied in two different ways, scalar and vectorally. So we just combine force and displacement, the two vectors into a scalar product and name the resultant number as another quantity work. Also trying to assign work, which is just amount of energy spent, a direction is meaningless.
