Chapter 9 Linear Momentum

Introduction – Our approach Introducing momentum and impulse Conservation of momentum Conservation of energy and/or momentum in collisions –elastic collisions in 1-D –inelastic collisions –collisions in 2,3-D Center of mass and Newton’s Second Law Comparing energy and momentum Problem solving

Momentum and Impulse Definition of momentum of an object Newton’s Second Law expressed in terms of momentum Impulse and the Impulse – Momentum Principle (or Relation or Theorem) Examples

Conservation of Momentum Momentum of a system defined Condition for Conservation of Momentum Statement of Conservation of Momentum Underlying symmetry of nature Examples

Conservation of Energy & Momentum in Collisions Elastic and Inelastic Collisions Examples/Discussion Elastic Collisions in 1-D Inelastic Collisions (perfectly, partially) Collisions in 2,3-D

Center of Mass and Translational Motion Center of Mass –Definition of Center of Mass (CM) –Finding the CM experimentally Expressing Newton’s Second Law for a System Examples

Energy & Momentum Three ways they are similar Three ways they are different Examples of their difference
