Some Important Concepts from Chapter 7

• What is momentum?
• How is it related to force? 
• What is required in order for momentum to be conserved? 
• What is an impulse and what is the result of an impulse? 
• What is the difference between an "elastic" and an "inelastic collision?" 
• Why do we say the total momentum is conserved in a collision? 
• Is momentum a vector or a scalar? 
• What does this imply about conservation of momentum? 
• What is a completely inelastic collision?  
• What is the center of mass of an object? 
• Is it always found inside the object? 
• How does the center of mass of an object move in a gravitational field?
