Q:

How do machines make work easier?

A:

Machines make work easier by changing the force on an object. Work occurs when an individual applies force to an object, and when a machine is used, the machine applies the force to the object instead of the individual.

Machines can also reduce the amount of time it takes to perform an action by increasing the amount of force to an object. One example of a simple machine is a pair of pliers. When the two large ends of the pliers are squeezed together, the smaller ends come together to apply a greater force to cut through an object. This force is greater than an individual could pinch.
