In long-range interacting systems, this velocity remains finite, but it can increase with the distance travelled. [2] [3] In the study of quantum systems such as quantum optics, quantum information theory, atomic physics, and condensed matter physics, it is important to know that there is a finite speed with which information can propagate. The ...
The optimal take off angle for a standing long jump (performed by a human) has been theoretically calculated to be ~22.6°, [7] substantially lower than the optimal take off angle for a projectile (i.e. 45°). [8] This is due to take-off speed decreasing with take-off angle due to the jumper's body configuration. [7]
The long jump is a track and field event in which athletes combine speed, strength and agility in an attempt to leap as far as possible from a takeoff point. Along with the triple jump , the two events that measure jumping for distance as a group are referred to as the "horizontal jumps".
Bell described the assumptions behind his work as "local causality", shortened to "locality"; later authors referred to the assumptions as local realism. [10] These different names do not alter the mathematical assumptions. A review of papers [11] using this phrase suggests that a common (classical) physics definition of realism is

Lewis' fourth round jump was wind-aided, but, at 8.91w m, it was the longest ever competition long jump in history, beating the existing wind-legal world record set by Bob Beamon at altitude at the 1968 Summer Olympics. Powell's wind-legal fifth round jump topped both, setting the world record at 8.95 m (29 ft 4.36 in).
The IAAF considers marks set at high altitude as acceptable for record consideration. However, high altitude can significantly assist long jump performances. At the 1968 Summer Olympics in Mexico City, Bob Beamon broke the existing record by a margin of 55 cm (21 + 1 ⁄ 2 in), and his world record of 8.90 m (29 ft 2 + 1 ⁄ 4 in) stood until Mike Powell jumped 8.95 m (29 ft 4 + 1 ⁄ 4 in) in ...
The size of the spheres does not change the results unless the increased weight exceeds the elastic limit of the material. If the solid balls are too large, energy is being lost as heat, because the elastic limit increases with the radius raised to the power 1.5, but the energy which had to be absorbed and released increases as the cube of the ...
