Objectives

Students will be able to:

• Students should be able to:

• List the three basic types of harmonic motion and give an example of each.

• Describe the properties that affect the period of motion for an object exhibiting simple harmonic motion.

• Be able to define all the vocaulary words and phrases associated wtih the unit. They include, but they are not limited to; frequency, period, amplitude, displacement from equilibrium, natural frequency, resonant frequency, bob, force constant, spring constant, Hz, cps, RPM and motion cycle.

• Identify the beginning and ending points for the pendulum arm’s length.

• Identify the name of the mass on the end of a pendulum.

• Describe what supplies the “restoring force” for a pendulum.

• Mathematically describe the effect of a pendulum’s mass on the period of motion.

• Mathematically describe the effect of the distance a pendulum is pulled back from its equilibrium position on the period of motion.

• Identify the variables used in the simple harmonic motion problems.

• Solve mathematical problems involving a pendulum’s harmonic motion’s formula.

• Solve pendulum problems utilizing ratio methods.

• Write the equation for a spring’s restoring force while identifying what each variable stands for and its units.

• Use a graph of restoring force versus displacement from equilibrium to calculate a spring force constant.
• • Solve mathematical problems involving a spring’s restoring force formula.

• Mathematically describe the effect of the distance, a mass attached to a spring’s end, is pulled back from its equilibrium position on the period of motion.

• Solve mathematical problems involving a pendulum’s harmonic motion’s formula.

• Solve spring problems utilizing ratio methods.

They drag them in like a picture. They play like movies. Some I reference and use via a web browser.
