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".
The special theory of relativity limits the maximum speed at which causal influence can travel to the speed of light, . Therefore, the principle of locality implies that an event at one point cannot cause a truly simultaneous result at another point.

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 ...
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 women's long jump was introduced over fifty years later in 1948, and was the second Olympic jumping event for women after the high jump, which was added in 1928. The Olympic records for the event are 8.90 m ( 29 ft 2 + 1 ⁄ 4 in) for men, set by Bob Beamon in 1968, and 7.40 m ( 24 ft 3 + 1 ⁄ 4 in) for women, set by Jackie Joyner-Kersee ...
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 ...
