What is the primary purpose of the ping pong ball cannon demonstration?

• To create a fun science experiment

• To show how loud a ping pong ball can be

• To demonstrate the physics of space

• To test the durability of soda cans

How does the mass of a ping pong ball compare to a tennis ball in the context of car crashes?

• Ping pong balls are much lighter

• Ping pong balls have the same mass as tennis balls

• Tennis balls are lighter

• Ping pong balls are heavier

Why is driving a larger car generally considered safer?

• Larger cars have more energy in a crash

• Larger cars have better visibility

• Larger cars are more fuel-efficient

• Larger cars are easier to maneuver

What is the role of crumple zones in modern cars?

• To increase the speed of the car

• To absorb impact energy and reduce G-forces

• To make the car more aerodynamic

• To improve fuel efficiency

What happens to a car made of celluloid in a crash?

• It remains intact

• It absorbs the impact without damage

• It shatters like glass

• It bounces back like a rubber ball

How does a vacuum help in accelerating the ping pong ball?

• By adding more air pressure

• By increasing the weight of the ball

• By making the ball heavier

• By reducing air resistance

What would happen if there was a small hole in the space station?

• Slow decompression over several minutes

• Nothing would happen

• The station would explode

• Immediate explosive decompression

What is the potential danger of being hit by a ping pong ball from the cannon?

• It could cause a minor bruise

• It could be fatal if it hits the head

• It would bounce off harmlessly

• It would have no effect

What safety precautions were taken during the ping pong ball cannon demonstration?

• No safety precautions were needed

• Only children were allowed to participate

• Safety goggles were worn and only adults participated

• The cannon was aimed at fragile objects

What was the surprising aspect of the ping pong ball's speed in the vacuum tube?

• It was slower than expected

• It was faster than expected

• It did not move at all

• It moved in the opposite direction
