Chapter 11, Woot Woot!

1. Features of harmonic motion

   • Type of motion in which an object moves along a repeating path
     • Pendulum Motions
     • Motion of the Earth as it orbits the sun

2. Spring mass Oscillator and Simple Pendulum

   • An object whose diameter is small compared to the length of the string and the string is massless, an object tied to a string makes up simple pendulum
     • Total force is parallel to the arc and is responsible for harmonic motion
     • the bottom point of the trajectory is the equilibrium position
     • Gravity and tension in the string act on the object
   • Position, Velocity, and Acceleration can be used to describe oscillatory motion
     • Also needed is period and frequency

3. Harmonic motion and energy

   • CH 12
   • The Mechanical energy is the sum of the Kinetic and Potential energies
   • For an ideal oscillator, the total mechanical energy is conserved
   • The maximum kinetic energy must also equal the potential energy

4. Hooke's Law

   • Chapter 10
   • The force exerted by the spring
   • F=-kx
