Exploring the Science Behind Olympic Bobsledding

What is the origin of the name 'bobsled'?

• It was named after a famous race in Switzerland.

• It was named after the sound it makes on the ice.

• It was named after the bobbing motion of the riders.

• It was named after its inventor, Bob.

What is the primary force that bobsledders experience during a run?

• Nuclear force

• Electromagnetic force

• Gravitational force

• Centripetal force

What is the main goal during the start phase of a bobsled race?

• To generate maximum acceleration

• To avoid air resistance

• To conserve energy

• To maintain a steady speed

What is the role of the team during the push phase?

• To reduce the sled's weight

• To generate as much force as possible

• To steer the sled

• To sit still and wait

What is the effect of a small advantage at the start of the race?

• It has no effect on the final time.

• It is maintained most of the way down the track.

• It only helps in the middle of the race.

• It is lost quickly.

How does gravity affect all bobsleds on the course?

• It accelerates all bobsleds in the same way.

• It affects them differently based on their mass.

• It has no effect on bobsleds.

• It only affects the bobsleds at the start.

What is the purpose of the bobsled's streamlined design?

• To increase the weight of the sled

• To reduce air resistance

• To make it look more attractive

• To increase friction with the ice

Why is it important to minimize air resistance during a bobsled run?

• To reduce the sled's temperature

• To increase the sled's weight

• To maintain the sled's speed

• To make the sled more visible

What happens when a bobsled scrapes against the ice wall?

• It becomes more stable

• It loses momentum

• It gains more speed

• It reduces air resistance

What is the challenge in finding the perfect racing line?

• It is always the shortest distance.

• It may create too much or too little friction.

• It is the same for every team.

• It is determined by the sled's color.
