This may help to add additional energy to the jump and improve on the standing vertical jump result. [2] In general, the standing vertical jump is the one that is used as an official measurement for athletes. [1]
Gravity. Trajectory of a ball bouncing at an angle of 70° after impact without drag , with Stokes drag , and with Newton drag . The gravitational force is directed downwards and is equal to [4] where m is the mass of the ball, and g is the gravitational acceleration, which on Earth varies between 9.764 m/s 2 and 9.834 m/s2.

"Each phase of the sequence included a 2-min warm-up, followed by 5 min of jumping. The four heights, measured by the distance the subjects’ feet were elevated above the trampoline bed, were 18, 37, 75, and 100 cm. A 5- to 10-min rest period was provided between each jumping level." The jump heights in inches were: 7", 14.6", 29.5" and 39.4".
