Science of the Winter Olympic Games - Engineering Competition Suits

The video discusses long track speed skating, highlighting Shani Davis's achievements and his potential to win a third consecutive gold medal. It explores the development of an advanced competition suit by Under Armour, designed to enhance aerodynamics and reduce friction and drag. The suit's design process involved motion-capture technology and wind tunnel testing. The video also explains the concepts of friction and drag, and how the suit aims to minimize these forces to improve performance.

What are the key attributes that define Shani Davis as a speed skater?

• Agility and balance

• Quickness, endurance, and skating prowess

• Speed and power

• Strength and flexibility

What materials are used in the advanced competition suits developed by Under Armour?

• Denim and linen

• Nylon, Spandex, and polyester

• Leather and silk

• Cotton and wool

What is the primary goal of designing competition suits for athletes?

• To make the athlete more aerodynamic

• To enhance the athlete's style

• To increase the athlete's weight

• To provide warmth during competition

What is the main impediment to a speed skater's progress on the track?

• Wind resistance

• Temperature

• Gravity

• Friction

What is drag in the context of speed skating?

• The force that propels the skater forward

• The resistance of the air moving across the skater's body

• The friction between the skater's blades and the ice

• The weight of the skater's suit

How did Under Armour test the effectiveness of different suit materials?

• By using wind tunnel tests with mannequins

• By conducting field tests on ice

• By analyzing video footage of races

• By surveying athletes' opinions

What is the final requirement for the competition suit in terms of athlete comfort?

• It must be lightweight

• It should be brightly colored

• It must be waterproof

• It should feel like a second skin
