Winter Olympic sports highlight various laws and principles of physics

A fast explainer on every Winter Olympic sport

Slalom, luge, skimo: The 16 sports at the Winter Olympics aren't the most familiar to everyday audiences. They can be divided into three categories: track, indoor, and outdoor. This video breaks down each sport's rules and quirks and the variations of its events in less than eight minutes.

The quintuple jump in figure skating is feasible, according to physics

As of 2025, many figure skaters feature jumps with four spins in their routines by achieving rotation rates of 400 RPM over 20 inches off the ground. By increasing one's rotation rate to about 430 RPM or jumping closer to three feet off the ground—a height reached by NBA players—five spins are possible.

One halfpipe skier qualified for the Olympics via loopholes

Freestyle skier Elizabeth Swaney reached the 2018 Winter Olympics by completing safe, trick-free halfpipe runs and accumulating ranking points in low-participation events. The story, told humorously in this brief video, highlights how qualification systems can reward persistence and rule optimization over peak athletic performance.

The magic angle to skip a spinning stone is 20 degrees

The traditional shoreside activity—reputedly practiced by luminaries Shakespeare and Homer—can be broken down into its bare physics, from hydrodynamics and momentum to gravity.

Conservation laws identify physical properties that remain unchanged in systems

The total amounts of properties like energy, charge, and angular momentum within a system have been experimentally observed to remain constant, even as changes occur. Particle interactions also conserve specific quantities, such as baryon and lepton numbers. Inconsistencies in these values within isolated systems have historically hinted at the existence of new physics.

Newton's laws describe how objects resist acceleration and respond to forces

Newton’s first law defines inertia as the tendency of an object to maintain its velocity. His second law connects external force, inertia, and acceleration, while his third law states that forces come in pairs—every action has an equal and opposite reaction.

Cold War rivalries fueled fierce competition in international sports

From Olympic medal counts to hockey showdowns, the US and USSR used sports to showcase ideological superiority. Athletic victories were framed as proof that each system—capitalist or communist—produced stronger, more disciplined citizens.

The steep and slippery Russian ice slides sparked centuries-long obsessions with thrill-seeking

When a French traveler happened upon the 17th and 18th century Russian pastime of sledding down man-made hills, he brought the idea home and inspired others to modernize the mechanics. Adoration for coasters spread around Europe and eventually reached the US, where the scream machine would undergo major advancements.

F1 drivers today are in peak physical shape

Formula 1 drivers today are in top physical condition, with reaction times on par with Olympic sprinters and strength programs specifically for their neck to withstand the immense g-forces experienced in racing.

Simulations suggest ice's slipperiness comes from rearranging molecules

Past models have proposed that slipperiness arises from a thin layer of liquid water formed at the ice's surface by frictional melting. However, new research suggests that electromagnetic forces between interacting surfaces push water molecules out of an ordered, crystalline structure and into a shapeless, soft, slippery layer. This process occurs solely through contact, independent of pressure or friction.

Davos is also one of Europe’s most well-known winter sports destinations

Davos emerged as a winter sports resort in 1865. The town went on to pioneer modern skiing, ski lifts, tobogganing, and ice sports. The city hosted early ski races, invented key lift technology, and became home to traditions like the Parsenn Derby and the Spengler Cup.

Why professional tennis players are so picky about balls before serving

Just as swimmers shave their bodies before competitions to swim faster, experiments show that tighter, less fluffy balls experience less drag forces when moving through the air and thus produce faster serves at the cost of less control. Players may select a fuzzier ball in scenarios that call for safer, more cautious play.

In a closed space, acceleration cannot be distinguished from gravity

Just as pressing into a door when in a car makes a turn resembles the feeling of being pushed from the side, Albert Einstein’s equivalence principle states that being in a gravitational field feels the same as when a floor accelerates up against you, as in a rocket.

'Viscoelasticity' allows muscles to be elongated briefly after stretching

The protective tissues around skeletal muscles consist of elastic proteins like collagen. Stretching them expands their length while retaining strength, ideal for athletes.

Swimming in schools helps some fish conserve energy in turbulent flows

Scientists studying groups of giant danios swimming in turbulent waters found that the fish used up to 79% less energy than they did when swimming individually in the same conditions. The same fish were found to use the same amount of energy in turbulent and calm water when in schools.

Solar sails use light as a means of propulsion

Photons possess momentum and can transfer it to objects they strike or bounce off, imparting radiative pressure, or a light-based force over a small surface area. Lasers fired at observational equipment with specially designed sails can theoretically use this mechanism to accelerate up to 20% the speed of light.

While exploring sneaker history and technology, Nye covers the science of structural design, air bubbles and materials, including algae foam. He once voiced a 20-minute guided run on the Nike Run Club app.

The law increased female participation in sports, along with Olympic medals

In the decades since Title IX’s passage, there has been a significant rise in female participation in high school (an increase of 239%) and college athletics (an increase of over 1000%). That pattern has led to changes in the highest levels of sport, with more American women winning Olympic medals in the Title IX era.

Ingenuity and advanced engineering have allowed trains to overcome extreme landscapes

The Jungfrau Railway utilizes electric trains powered by hydroelectric energy to ascend the Swiss Alps, while Poland's Elbląg Canal hauls ships along cable-powered tracks driven by waterwheels. Germany's Wuppertal monorail navigates bends as it glides over a river valley, and New Mexico's Holloman High-Speed Test Track can achieve speeds of Mach 8.6 for rocket sleds.

While the sun's gravity keeps the planets in orbit, their gravity also pulls on the sun, causing it and everything else in the solar system to orbit around a mutual balance point called the barycenter—the true center of the solar system.

Performance art differs from other performances, like dance and theater

While performance art is a very flexible genre, it is defined by several core elements: time, space, the body, and the relationship between the artist and the audience. These elements may be manipulated in infinite ways to convey the artist’s message, such as how endurance performances challenge the limits of the body over long periods of time.

Berenson's frailty led her to basketball
