What is the effect of simple machines on work?

Simple machines, such as levers, pulleys, and inclined planes, make work easier by allowing a smaller force to be applied over a longer distance to achieve the same effect as a larger force applied over a shorter distance. They reduce the amount of force needed to move an object, effectively increasing efficiency. While the total amount of work done (force times distance) remains constant, simple machines change how that work is performed, allowing tasks to be completed with less effort.
