Work is defined as the transfer of energy that occurs when a force is applied to an object and causes it to move a certain distance in the direction of the force. The amount of work done is calculated by multiplying the force applied by the distance the object moves in the direction of the force.

When a constant force is applied to an object, the work done can be calculated using the formula:

Work = Force x Distance

In this case, the force remains constant throughout the movement of the object, and the work done is simply the product of the force and the distance the object moves.

On the other hand, when a variable force is applied to an object, the work done is calculated by integrating the force over the distance the object moves. This means that the force applied may change as the object moves, and the work done is the sum of the force applied at each point along the path of movement.

In both cases, the work done is a measure of the energy transferred to the object by the force applied, and it can be used to determine the amount of energy required to move an object over a certain distance.
