In physics, the pivot about which a lever turns is generally known as a what?
Lever a fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. Assuming the lever does not dissipate or store energy, the power into the lever must equal the power out of the lever. As the lever rotates around the fulcrum, points farther from this pivot move faster than points closer to the pivot. Therefore, a force applied to a point farther from the pivot must be less than the force located at a point closer in, because power is the product of force and velocity. If "a" and "b" are distances from the
Pivot turn Pivot turn In dance, a pivot turn (or simply pivot) is a general classification for dance turns in which the performer's body rotates about its vertical axis without traveling. The performer may be supported by one or both feet, which swivel in place during the pivot turn. In some dance genres, a pivot on both feet is called a "twist turn". Pivot turns are commonly named as such in ballroom dancing, folk dancing and ethnic dances. In many other dance genres, pivot turns are known by specific names and typically are not referred to as pivots. For example, in ballet,
