Which of the following describes work?

Energy acts on an object.

Force acts on an object and causes a displacement of that object.

Force acts on an object.

Friction only acts on an object and causes a displacement of that object.

Force acts on an object and causes a displacement of that object.

Explanation:

Work Is said to be done on an object when a force causes the object to move a displacement.

For example, if a force of F Newton's acts on an object and then cause the object to move or go in a certain direction say x meters, the workdone by the force on the object can be calculated using the formula that shows the relationship between the force and the displacement the object covers as a result of the force.

This is given as

Workdone = force x distance

Therefore the workdone on the object can be said to be

W. d. = FN x xmeters

Workdone is measured in Joules
