Question

He diagrams above show two vectors. One is a force vector and one is a displacement vector.

Which of the diagrams above shows a situation in which zero work is being done?

Answer 1

A, C

Step-by-step explanation:

In order for work to be done, the applied force has to be in the same direction as the displacement, so the diagrams showing work being done are B and D.

In A, no work is done because the directions of the force and displacement are at 90° .

In C, no work is done because the force and displacement are in opposite directions.
