The Physic of One of the Craziest Big Air Snowboard Tricks Ever

Behold the stomach-clenching spectacle of the quadruplet cork 1800. The dizzying snowboarding trick–first territory by British Olympian Billy Morgan, above–involves propelling off a ramp into four off-axis flips( called corks) and five full rotates. Merely four parties had already been completed the 1,800 -degree stunt. But this month in Pyeongchang, South Korea, expect to see more attempts as elite wintertime jocks compete in the Olympic debut of Big Air, an contest in which boarders barrel off a 110 -foot-tall ramp to perform apparently impossible throws and twirls. We enlisted physicist John Eric Goff, author of Gold Medal Physic: The Science of Sports, to break the forces at gambling behind the quadruplet cork 1800.

1 Launch

Olympic boarders will accelerate down 240 feet of descent, 39 positions at its steepest, before hurling off the ramp. Speed is key here: Too slow, and they won’t get enough breath to ended four throws. Goff reckons Morgan makes nearly 40 mph at takeoff.

2 Initiate Spin

Achieving the quadruplet cork’s difficult combination of flip and revolve requires a simultaneous trunk twisting and abdominal crunch. That speedy change likely makes about 50 foot-pounds of torque, 1,000 seasons the torque it takes to turn your head.

3 Optimize Posture

As his form spiralings through the breeze, Morgan crouches and grabs his timber. The smaller he can tuck–minimizing the moment of inertia–the faster he rotates. During the first cork, he sheds his left forearm out to the side to adapted his rotational direction.

4 Achieve Speed

Morgan plucks both of his arms into his chest like a twirling flesh skater to pick up the pace. He needs to spin as quickly as possible to complete all five spins before touchdown, averaging a whiplash-inducing 1.7 changes per second.

5 Brace for Impact

As he completes the last stopper, Morgan hurls out his arms and arranges his figure to slow the spin. He touches the dirt croaking approximately 50 mph with about 450 pounds of violence on each leg, Goff says, about half the force it takes to rupture a bone.

6 Stick It

Morgan lands with his board at a 14 -degree angle to decelerate gradually. He crouches his knees as he strokes down, which extends his collision time and gives the force. All told, he executes the ploy in 2.9 seconds of hang hour, soaring 133 paws over the snow.

Flippin’ Awesome

Ready for more stupid throw physics? Here’s what goes into a flawless triple cork 1620.

In the case of both moves, it takes a carefully engineered ramp to keep equestrians safe–and minimize the equivalent fall height of their descents back to Earth.
