The take off was examined by a two dimensional motion analysis system. The average angle of the knee joint bend during long jump take off is 192.2 ± 22.4 and the average angle of the knee joint bend ...

Along a streamline on the centerline, the Bernoulli equation and the one-dimensional continuity ... along the direction of motion. An easy demonstration of the lift produced by an airstream requires a ...

As a result, they only generate lateral motion. To get two-dimensional motion from one motor, the researchers shifted the coils so the lower horizontal part of the coils sits in the magnetic field ...
