Answer:

When the force is applied on any object in a fixed direction and gets displaced by its previous position. We can consider it as the work.

Explanation:

More about the concept :

• The term work was created by Gaspard Gustave Coriolis in 1930s who was a French.

• Work which is done on any object depends on displacement.

• Work also depends on the exerted force over it.
