What is momentum?

• Momentum is the force applied to an object.
• Momentum is the mass times the velocity of an object.

• Momentum is the speed of an object in motion.
• Momentum is the distance traveled by an object.

Which is an example of Newton's Third Law of Motion in a car crash?

• The car crumples without any force being applied.
• The car and the object exert equal and opposite forces on each other during the crash.
• The car accelerates away from the crash site.
• Passengers continue moving forward when the car stops suddenly.

Which is an example of Newton's First Law in a car crash?

• The airbags deploy to protect the passengers.
• Passengers continue moving forward when the car stops suddenly.
• Passengers are safely restrained by seatbelts.
• The car and the object exert equal and opposite forces on each other during the crash.

• Newton's First Law of Motion
• Law of Universal Gravitation
• Newton's Third Law of Motion

Why is it important to lengthen the time of impact in a car crash?

• It increases the speed of the vehicle during a crash.
• It reduces the force experienced by occupants, minimizing injuries.
• It makes the car more likely to roll over.

What is an example of impulse in a car crash?

• The type of fuel used by the car.
• The speed of the car before the crash.

How many collisions does one body experience during a car crash?

• Two collisions, first between the car and object, next between the body and the car

• No collisions
• Three collisions, first between the car and object, next between the body and the car, third between the organs, tissues and bones inside the body.

• One collision between the car and the object

What is impulse in science?

• Impulse is the distance traveled by an object.
• Impulse is the force times the time over which it acts, resulting in a change in momentum.

• Impulse is the speed of an object over time.
• Impulse is the mass times the speed of an object in motion.
