To lift a load off the ground, the force required is equal to the weight of the load. In case of a lever, however, a small effort force can be used to lift a much heavier load. How is this possible?
Levers use the weight of the load combined with the effort to lift the load.
Levers combine the weight of the load with the force of gravity to lift the load.
Levers reduce the force required by increasing the distance over which the force is applied.
Levers distribute the load over their length, thereby reducing the force required to lift the load.
