Car Science

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.

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.
