on means you are on top of something, and at means you are at something... on: on top, at meaning: there. You can say: I am on the seesaw. you are riding or ontop the seesaw. I am at the seasaw: means: i am currently right there, where the seesaw is. Hoped this helped...
force multiplier
fulcrum force and load
A seesaw in physics is a Class 1 Lever. One rider can be called the force, the other rider is then the load, and the fulcrum is between the two.

first class lever. Why? because it is in the order of output force-fulcrum-input force. output force ______________________________ input force fulcrum

A seesaw is an example of a first-class lever. The fulcrum, which is the part of the lever that does not move, is in the middle. The resistance, which is the weight (person) you are trying to lift is at one end. The effort, which is the force applied to the lever, is the person sitting on the other end.

A seesaw is a class one lever.
a seesaw is a lever that is balenced on a fulcrum
A seesaw is a basic lever and by definition it has a fulcrum. Without the fulcrum, there would be no point for the seesaw to operate on.
