Car Crash Physics

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.

• The color of the car involved in the accident.

• The change in momentum of the car during the collision.

Seatbelts are made to "give" on impact. This feature is related to which of Newton's Laws of Motion?

• Law of Universal Gravitation

• Newton's Second Law of Motion

• Newton's First Law of Motion

• Newton's Third Law of Motion

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.

The tendency of objects to resist a change in motion is called:

• Friction

• Inertia

• Gravity
