Friction, I think.
You can decrease the force needed to lift a load with a lever by increasing the length of the lever arm. By moving the pivot point or fulcrum closer to the load, you can reduce the amount of force required to lift the load.
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.
The position of the fulcrum affects the mechanical advantage by changing the ratio of the input force to the output force. Moving the fulcrum closer to the load increases the mechanical advantage, making it easier to lift the load. Conversely, moving the fulcrum closer to the effort force decreases the mechanical advantage, requiring more effort to lift the load.
Moving the fulcrum changes the mechanical advantage of the lever. Placing the fulcrum closer to the load increases the force needed to lift the load but allows for greater distance and speed. Moving it closer to the effort reduces the force needed but decreases the distance and speed.
That's actually only possible in a First Class lever. In that case, moving the fulcrum closer to the load makes it easier to lift the load, since it now takes less force at the effort end. But the effort force also has to move through a greater distance than it did before, in order to lift the load to the same height.

Lever is used in moving a load around a pivot using a force.

A third-class lever is typically used to move a load of dirt, with the effort (force applied) being in between the load (the dirt) and the fulcrum (pivot point). This lever arrangement allows for more force to be exerted to move the load with less effort.
When the pivot point of a lever changes, it can affect the mechanical advantage of the lever. Moving the pivot closer to the load decreases the force required to lift it but increases the distance over which the force must be applied. Conversely, moving the pivot closer to the effort force increases the force required to lift the load but decreases the distance over which the force must be applied.
Examples of a load in physics include the weight of an object, the force exerted on a structure, or the tension in a cable or rope. Loads can be static, such as the weight of a book resting on a table, or dynamic, such as the force of a moving car on a bridge.
Moving a heavy load is an example of mechanical work being done, where a force is applied to an object to displace it over a distance. This work involves transferring energy to the object to overcome its weight and frictional forces.
In a fishing rod, the load is the force of the fish pulling on the line, the fulcrum is the point where the rod bends to absorb this force, and the effort is the force applied by the angler to reel in the fish. The load and effort are balanced at the fulcrum point to allow for efficient fishing.
Moving water is a major force in the transport of sediment. The force of water helps to erode, transport, and deposit sediment in various environments like rivers, streams, and coastlines. The energy of moving water can vary depending on factors such as velocity, volume, and sediment load.
