Under which condition is no work done?
A. A force pushes an object and slows it down.
B. A force pulls an object and speeds it up.
C. A force pulls down on an object that moves downward.
D. A force pushes up on an object that stays in place.
Answer (1)
In physics, work is only done when an object moves in the direction of the applied force. The scenario where a force pushes up on an object that stays in place results in no movement, meaning no work is done. Thus, the answer is that no work is done when the object remains stationary despite the force applied. ;
