What is the definition of a fulcrum in relation to a lever?

A fulcrum is best defined as the fixed point around which a lever pivots. In the context of a lever, the fulcrum plays a crucial role as it allows the lever to rotate and lift the load. When force is applied at one end of the lever, the lever moves around the fulcrum, enabling it to exert a greater force on the load positioned on the other side. This principle of leverage is fundamental in understanding how levers operate and the mechanical advantage they provide.

The other options describe elements related to the function of a lever but do not accurately capture the definition of a fulcrum. The distance from the lever to the load pertains to the lever arm, while the weight lifted refers to the load itself, and resistance relates to the opposing force that the lever works against. None of these elements define the pivotal point, which is essential for the lever's function.
