2/14 Quiz

What is one of the key considerations when debating speed limits?

• Only how fast cars can go
• B) Both scientific safety data and societal impacts
• C) The popularity of speed limits in other countries
• D) How many people own sports cars

Why do higher speed limits pose a greater safety risk?

• A) They make fuel consumption more efficient
• B) They decrease stopping distances, reducing crashes
• C) They increase the force of impact in a collision
• D) They improve vehicle handling

What do engineers consider when designing vehicle safety features?

• A) Only the strength of the car's frame
• B) A combination of energy transfer, impact force, and stopping time
• C) Just how fast the car can go before becoming unsafe
• D) The number of airbags a vehicle has

Explain how Newton’s Laws of Motion relate to the importance of speed limits in vehicle safety.

Describe how vehicle crumple zones and braking systems work together to reduce injuries in high-speed crashes.

Using physics principles, explain why a higher velocity leads to a more dangerous collision.

A less-rigid and longer crumple zone will:

• A) Increase the peak force acting on the vehicle occupants
• B) Reduce peak forces by increasing the time over which the vehicle stops
• C) Make the vehicle stop instantly
• D) Have no effect on the crash outcome

When energy transfers to the crumple zone, what happens to the material?

• A) It stays the same and does not change shape
• B) It deforms, absorbing the energy of the crash
• C) It increases the force felt by passengers
• D) It makes the car bounce back harder

How does a longer stopping time impact the force felt by a passenger?

What is the primary purpose of a vehicle’s crumple zone?

• A) To make the car heavier for better stability
• B) To reduce the force experienced by occupants during a collision
• C) To increase the speed of the vehicle during a crash
• D) To prevent the car from crumpling at all
