Question

If work done is scalar quantity how can work done be negative in some cases
(Physics)

Answer 1

Answer:

Hi

Step-by-step explanation:

If the displacement is in the direction of the force, then work is positive. If the displacement is in the opposite direction of the force, then work is negative. If the displacement is perpendicular to the direction of the force then work is zero. So, the work done depends on direction.

Note one thing we are doing dot product of two vectors(Force and displacement) and dot product of two vectors is always a scalar ,that is why work done is scalar....but this doesn't make displacement and force a scalar quantity and that's why even if work done is scalar it can be negative due to displacement...
