Question
When is positive work being done?
- When the direction of force and distance covered is the same
- When the direction of force and distance covered is different
- When the direction of force and distance covered is perpendicular
- When the direction of force and distance covered is the same
Hint:
When the direction of force and distance covered is the same
The correct answer is: When the direction of force and distance covered is the same
when force and displacement are in the same direction, work done is positive.
