Question
How do simple machines make work easier?
a. They reduce the amount of force needed to move an object to do the same amount of work
b. They magnify the force being applied, thereby decreasing the work they can do with no extra energy exerted by the person using the machine.
c. They increase the distance over which a force is needed, doing more work with less force
d. They decrease the distance needed between a person and an object, allowing the person to apply more force and do more work

The correct answer is:
**a. They reduce the amount of force needed to move an object to do the same amount of work.**
Simple machines, such as levers, pulleys, ramps, and inclined planes, are designed to make it easier to perform work by allowing a smaller force to be applied over a longer distance, effectively decreasing the effort needed to move an object.
