A force acting upon an object to cause a displacement is known as

Work

Explanation:

Work is said to be done in case an object experiences a force that leads to its movement from its initial position. Basically work is depended on three factors –  

a)Force applied on the object

b)Direction and angle of force application

c)Displacement of the object  

The simple formula for work is  

Where

W signifies the work done

F signifies the force applied and

is the angle of force application

WORK

Explanation:

When the force is applied on an object that causes some displacement in the body then this incident is called work.

When the displacement is in the direction normal to the direction of force then the work done is zero this is because the work done is given as:

where:

F = force

s = displacement

angle between the force and the displacement
