What Kind of Simple Machine Is a Seesaw?

Answer

A seesaw is a special type of simple machine that allows people to teeter back and forth around a pivot point. Classified as a lever fulcrum, this kind of simple machine uses weight to move objects up and down around a point. This is what allows the seesaw to move effortlessly as the weight is counterbalanced evenly.
