Newton's Third Law Demonstration Questions

NASA astronaut Mark Vande Hei explains Newton's Third Law aboard the International Space Station. He demonstrates the law using a basketball and himself, highlighting the effects of mass disparity. The video also shows how similarly massed objects interact in space, illustrating the law's principles in microgravity. Viewers are encouraged to test the law on Earth.

What is the main topic discussed in the video?

• Newton's First Law

• Newton's Law of Universal Gravitation

• Newton's Second Law

• Newton's Third Law

According to Newton's Third Law, what happens in every interaction between two objects?

• No forces are experienced by either object

• Both objects experience equal and opposite forces

• Both objects experience forces in the same direction

• Only one object experiences a force

In space, how do thrusters steer a vehicle?

• By expelling gas in the same direction as the desired movement

• By using magnetic fields

• By expelling gas in the opposite direction of the desired movement

• By changing the vehicle's mass

What is the first object used in the basketball demonstration?

• A basketball

• A baseball

• A tennis ball

• A football

What happens when a force is applied to the basketball in space?

• The astronaut accelerates significantly

• Both the basketball and astronaut do not move

• The basketball accelerates significantly

• The basketball does not move

Why does the astronaut not accelerate much when applying a force to the basketball?

• Because there is no gravity in space

• Because the basketball is too heavy

• Because the astronaut has a much larger mass than the basketball

• Because the astronaut is not applying enough force

What is the key difference between the two objects in the first demonstration?

• Mass

• Material

• Color

• Shape

What is the purpose of using similarly massed objects in the second demonstration?

• To show that Newton's Third Law does not apply

• To prove that mass does not affect acceleration

• To demonstrate that the forces are not equal

• To show that both objects will accelerate equally

What happens when the astronaut applies a force to Joe, who has a similar mass?

• Only Joe accelerates

• Only the astronaut accelerates

• Neither Joe nor the astronaut move

• Both Joe and the astronaut accelerate away from each other

What should viewers do after watching the demonstration in space?

• Test Newton's Third Law on Earth

• Ignore the information

• Forget about Newton's Third Law

• Try to go to space
