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.

Seat belts are a safety feature most related to which of Newton's Laws of Motion?

• Newton's First Law of Motion

• Law of Universal Gravitation

• Newton's Third Law of Motion

• Newton's Second 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 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.
