Question
In each of the following a force, F is acting on an object of mass, m. The direction of displacement is from west to east shown by the longer arrow. Observe the diagrams carefully
and state whether the work done by the force is negative, positive or zero.
Answer
Here is the answer based on the three diagrams from left to right:
First Diagram: Work done is Zero (Force is perpendicular to displacement).
Second Diagram: Work done is Positive (Force acts in the direction of displacement).
Third Diagram: Work done is Negative (Force acts opposite to the direction of displacement).
