Summary of Material in Chapters 10-12

• elastic collision, inelastic collision
• center of mass
• torque, angular momentum (classical mechanics version)
• central force
• translational and internal kinetic energy
• orbital and spin angular momentum
• moment of inertia
• Hooke's law
• harmonic oscillator

You should understand the following topics:

• Newton's third law and conservation of momentum
• Elastic and inelastic collisions
• Open systems and Newtonian mechanics, e. g., rockets, conveyor belts, etc.
• Torque and angular momentum -- three-dimensional version
• Newton's 2nd law for rotation
• Separating kinetic energy and angular momentum into parts associated with the overall motion of the center of mass of multiple particles and the motion relative to the center of mass.
• Statics
• Estimating the period of oscillators from energy considerations
• Finding the oscillation frequency of harmonic oscillators using Newton's equations to construct a differential equation
• The forced oscillator
