Q: If the amount of force of that is applied is increased, what happens to the work that a machine is producing?


Read this paragraph and choose the correct option from the provided answers:

Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. Contrary to popular belief, machines do not increase the amount of work that is done. They just change how the work is done. So if a machine increases the force applied, it must apply the force over a shorter distance. Similarly, if a machine increases the distance over which the force is applied, it must apply less force.

 Choices:

- it's unchanged

- it is harder

- it's variable

- it is easier


A:
it is easier
