Chapter 6 Objectives Identify different types of collisions.
Section 3 Elastic and Inelastic Collisions Chapter 6 Objectives Identify different types of collisions. Determine the changes in kinetic energy during perfectly inelastic collisions. Compare conservation of momentum and conserva-tion of kinetic energy in perfectly inelastic and elastic collisions. Find the final velocity of an object in perfectly inelastic and elastic collisions.

Chapter 6 Elastic Collisions Elastic Collisions Momentum is Conserved
Section 3 Elastic and Inelastic Collisions Chapter 6 Elastic Collisions Elastic Collisions Momentum is Conserved Kinetic Energy is Conserved

total initial momentum = total final momentum
Section 3 Elastic and Inelastic Collisions Chapter 6 Collisions Inelastic collision Momentum is Conserved Kinetic Energy is not Conserved Perfectly inelastic collision Inelastic collision in which two objects stick together after colliding and move together as one mass Conservation of momentum for a perfectly inelastic collision: m1v1,i + m2v2,i = (m1 + m2)vf total initial momentum = total final momentum

Perfectly Inelastic Example
Section 3 Elastic and Inelastic Collisions Chapter 6 Perfectly Inelastic Example A railroad flatcar of mass 2,000 kilograms rolls to the right at 10 meters per second and collides with a flatcar of mass 3,000 kilograms that is rolling to the left at 5 meters per second. The flatcars couple together. What is their speed after the collision?
