TEXTBOOK:  Chapter 13, Sections 13.1 to 13.6, pages 404 - 421.

OBJECTIVES:

• Determine the spring constant for a spring and verify Hooke's Law.

• State how the total energy of an oscillating system depends on the spring constant and the amplitude of motion.

• Explain how the kinetic, potential, and total energies are related as a system vibrates. Solve problems involving the interchange of energy in an oscillating system.

• Explain the meaning of the following words for a mass vibrating at the end of a spring: amplitude, displacement, frequency, period.

• Define simple harmonic motion in terms of restoring force (or acceleration) and displacement.

• Derive a formula for acceleration (in SHM) from Newton's second law and Hooke's law. 

• Explain how motion in a reference circle and sinusoidal motion are related to simple harmonic motion.

• State and apply the relationship between frequency and period for simple harmonic motion.

• Determine the amplitude, period, and frequency if given a sinusoidal curve of displacement as a function of time.

• Identify points in the motion of a simple harmonic oscillator where the velocity is zero or where it achieves its maximum positive or negative value.

• Identify points in the motion of a simple harmonic oscillator where the acceleration is zero or where it achieves it maximum positive or negative values.

• Draw a force diagram for the simple pendulum and derive the expression for the period of a simple pendulum.

• Solve problems using the formula for period of a pendulum.

• Test the effect of certain variables on the period of a pendulum. 

• Use a computer or graphing calculator to find the relationship between two variables.
