Answer;

Reduces the amount of work needed to move an object.

Explanation;

• A simple machine is any device that reduces human effort to do work. They include, levers, inclined plane, pulleys, etc.
• Simple machines make work easier by multiplying, reducing, or changing the direction of a force and also by changing the distance the force acts through.
