Some Important Concepts from Chapter 8

• What unit of angular measurement is used to describe angular motion? Why?
• What are the angular quantities that are analogous to distance, velocity, and acceleration? 
• What is torque? 
• What is required to produce a torque? 
• What effect does a net torque produce? 
• What is the moment of inertia?
• What is angular momentum? 
• What is required in order to change angular momentum? 
• Describe the similarities and differences between torque and force, moment of inertia and mass, angular kinetic energy and kinetic energy, and angular momentum and linear momentum. 
• What is an inertial reference frame and a non-inertial reference frame?
