The position of the fulcrum affects the amount of force required to lift a load. Moving the fulcrum closer to the load reduces the force needed, while moving it farther away increases the force required. Placing the fulcrum at different distances changes the mechanical advantage of the lever system.
how does moving a fulcrum on a lever change the amount of force needed to move an object
Yes, the position of the load on a class-2 lever does affect the amount of effort required. Moving the load closer to the fulcrum reduces the effort needed, while moving it farther away from the fulcrum increases the effort required.

shearing
The amount of effort required to lift a load is inversely proportional to the distance the load is from the fulcrum. This means that the closer the load is to the fulcrum, the more effort is needed to lift it, and vice versa when the load is farther from the fulcrum.
shearing
A fixed point at which a lever pivots is called a fulcrum. The location of the fulcrum determines how the lever will move and can affect the amount of mechanical advantage gained when using the lever.
The amount of effort needed to lift a load decreases as the distance of the load from the fulcrum increases. This is because a longer distance from the fulcrum provides a mechanical advantage, making it easier to lift the load.
The length from the fulcrum to the load is known as the load arm or effort arm. It is the distance between the fulcrum and the point where the force is applied to lift the load. This length affects the amount of force needed to lift the load.
The total amount of energy remains constant when it changes from one form to another, according to the law of conservation of energy. Energy can neither be created nor destroyed; it simply changes from one form to another.
