Of course with a human jump, I can look at the total time off the ground (the hang time) as well as the jump height. Since the only force acting on a real human on the real Earth is the gravitational ...

In a fixed-field alternating-gradient (FFAG) accelerator, eliminating pulsed magnet operation permits rapid acceleration to synchrotron energies, but with a much higher beam-pulse repetition rate.

\(\Delta v\) (pronounced 'delta v' is the change in speed of the object. Acceleration is measured in metres per second per second or metres per second squared \(m\, s^{-2}\). A sprinter starting at ...
