If work done is a product of force and displacement and force is a vector then why isn't work done a vector quantity, when work done is also positive and negative?

Solution

Work Done is a scalar quantity because it is a dot product of two vector quantities, namely, force and displacement. Like any scalar quantity work done can both be positive and negative and it doesn't have to be a vector to be so.
