Question

For work to be done on an object:

*
The work input must be equal to the work output
The energy input must be equal to the energy output
Only a force must be applied, moving the object is not required
The object has to move a distance when a force is applied to it

Answer 1

The object has to move a distance when a force is applied to it

Step-by-step explanation:

For work to be done on a body the force applied must move the body through a particular distance.

Work done = Force x distance

If no distance is moved by the force, no work is done.

Also, the angle between the force and the distance must be 0 to do the maximum work on the body.
