Answer:

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

Step-by-step 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
