Question

list two conditions which need to be satisfied for the work to be done on an object

Answer 1

1.For work to be done , the force must be applied and must not be zero.

2.work is done when the object moves through a certain distance in a particular direction after the force had been applied on it.

Answer 2

The conditions which need to be satisfied for work to be done on an object are as follows:

• A non-zero force must be acting on the body for non-zero work.
• The force applied on the object must produce a non-zero displacement for non-zero work.
• If either of the above conditions are not satisfied, then the work done on the object will be considered as zero otherwise it will be the product of force and displacement.
