Skaters seem to have found a way to defy the laws of physics, but they're actually using these laws to perform cool skateboard tricks.
The Physics of the Ollie 6z4v67
To perform an
sneakers in mid-air. The physics behind the ollie is called
rotation around multiple axes. Three forces act on the skateboard just before the skater jumps:
the weight of the skater.
the force of gravity on the skateboard.
the force of the ground pushing up on the skateboard.
These three forces balance out to
zero, which is why the skateboard rolls along at a constant
speed. The skater also needs to crouch down in order to do an ollie because a
low center of mass is essential to jumping high.
The Physics of Pumping in a Halfpipe 5x351p
The faster a skater goes in a
greater height at the top of the ramp or halfpipe.
The Physics of the Frontside 180 3g6x3r
Skaters perform the frontside 180 by flying into the air from the top of a
skateboarder uses his arms as torque to turn himself around in mid-air, pulling off the trick.
