How is work calculated?

• Work is calculated by multiplying the force applied to an object by the distance over which the force is applied.

• Work is calculated by subtracting the force applied to an object from the distance over which the force is applied.

• Work is calculated by adding the force applied to an object to the distance over which the force is applied.

• Work is calculated by dividing the force applied to an object by the distance over which the force is applied.
