Answered by GPT 3.5
An external force must be applied to the object in order for work to be done. This force must cause the object to move in the direction of the force. Work is defined as the product of the force applied to an object and the distance over which the force is applied.
Answered by GPT 3.5
No, work has not been done in this case. Work is only done when a force is applied to an object and the object moves in the direction of the force over a certain distance. If the object returns to its original position, then there has been no net change in the object's position and therefore no work has been done.
