If force is applied at an angle to the direction of displacement of a body, how will you derive the amount of work done?
1. When force is applied at an angle to the direction of displacement, work done is given as —
2. Based on the value of the angle between force and displacement work done can be positive, negative or zero.
Value of | Value of | Nature of work done |
