1253 - What is the relationship between force moment and lever?

Imagine you have a seesaw. A lever is like a long board that can pivot (turn) at a point, and a force moment is the turning force around that point.

The relationship between force moment and lever is this: when you apply force to a lever, it creates a force moment that makes the lever turn around the pivot point. The closer the force is applied to the pivot point, the weaker the force moment. The farther away the force is applied, the stronger the force moment.

Think of it like this: if you sit close to the pivot point on a seesaw, you needs to be very heavy to make someone on the other side move. But if you sit far away from the pivot point, even if you're not that heavy, you can make the other person lift off the ground. That's because the force moment is stronger when the force is applied farther away.
