Science of the Winter Olympics - Aerial Physics

The video tutorial explores the physics behind Olympic freestyle aerial skiing, focusing on three twisting techniques: contact twisting, moment of inertia control, and tilt twisting. Emily Cook and physicist Paul Doherty explain how skiers use these techniques to perform complex aerial maneuvers. The tutorial also draws parallels with the natural world, such as how cats twist in mid-air. The video emphasizes the importance of angular momentum and the role of arm and leg movements in controlling spins.

What is the primary force that initiates a twist in freestyle aerial skiing?

• Gravity

• Push-off from the ramp

• Body weight

How do aerialists control their spin once they are airborne?

• By using external tools

• By altering their weight

• By adjusting their moment of inertia

• By changing their speed

What animal is used as an example to explain the concept of twisting in mid-air?

• Dog

• Cat

• Monkey

• Bird

What technique involves using arm movements to change the speed and direction of a spin?
