Mastering Safe Falls in Extreme Mountain Biking

The video introduces Antoine, a stuntman skilled in falling safely, and explores techniques to fall without injury. Vanson attempts free riding, guided by Antoine, and learns about protective gear. Richard Holman introduces an anti-shock material, demonstrating its effectiveness using non-Newtonian fluid properties. The video emphasizes the importance of safety in extreme sports.

What is the main reason Antoine wears a protective brace?

• To look more professional

• To protect his neck and cervicals

• To keep warm during rides

• To enhance his performance

What is the key technique to safely fall during free riding?

• Jumping off the bike

• Stopping abruptly

• Cushioning the fall by rolling

• Leaning backward

What is the purpose of the anti-shock polymer material introduced by Richard Holman?

• To offer enhanced protection against impacts

• To provide better grip

• To improve bike speed

• To reduce weight of the equipment

What experiment was conducted to demonstrate the effectiveness of the anti-shock material?

• Throwing the material against a wall

• Dropping a metal ball on a tile

• Riding a bike over a ramp

• Heating the material

What is a non-Newtonian fluid?

• A fluid that evaporates quickly

• A fluid that behaves like a gas

• A fluid that always behaves like a solid

• A fluid that can behave like both a liquid and a solid

How does a non-Newtonian fluid react to sudden impact?

• It becomes more liquid

• It remains unchanged

• It solidifies to absorb the impact

• It evaporates

What happens to the molecules in a non-Newtonian fluid during an external attack?

• They become gaseous

• They disperse randomly

• They evaporate

• They form a solid defense
