Question

How do simple machines make work easier?

A. They magnify the force being applied, thereby decreasing the work they can do with no extra energy exerted by the person using the machine.
B.They decrease the distance needed between a person and an object, allowing the person to apply more force and do more work.
c. They reduce the amount of force needed to move an object to do the same amount of work.
D. They increase the distance over which a force is needed, doing more work with less force.

C. They reduce the amount of force needed to move an object to do the same amount of work.

Simple machines such as levers, pulleys, wheels, and ramps allow for the distribution of force over a larger area, making it easier to move objects or complete tasks with less effort. This principle is based on the concept of mechanical advantage, where the machine multiplies the input force to achieve a greater output force. By reducing the amount of force required to perform a task, simple machines make work easier for the person using them.
