AP Physics 1: Linear Momentum and Impulse Review

The video covers the concepts of momentum and impulse, essential for the AP Physics One exam. It explains momentum as a vector quantity, conserved in collisions and explosions, and distinguishes between elastic and inelastic collisions. Newton's second law is related to impulse, highlighting its role in safety equipment like airbags. The video concludes with a preview of rotational kinematics.

What is the vector nature of momentum attributed to?

• Mass

In which type of collision is kinetic energy conserved?

• Elastic collision

• Perfectly inelastic collision

• All types of collisions

• Inelastic collision

Which of the following is NOT a type of collision discussed?

• Perfectly inelastic collision

• Inelastic collision

• Elastic collision

What is the symbol typically used for impulse?

• Uppercase P

• Lowercase j

• Uppercase J

• Lowercase p

What is the relationship between impulse and momentum?

• Impulse is the difference between force and time

• Impulse is the sum of initial and final momentum

• Impulse is the change in momentum

• Impulse is the product of force and distance

How does an airbag reduce the force of impact during a collision?

• By decreasing the mass of the body

• By increasing the speed of the body

• By increasing the time of impact

• By decreasing the speed of the body

What is the primary purpose of safety equipment like airbags?

• To increase the time of impact

• To decrease the speed of the body

• To increase the speed of the body

• To change the mass of the body
