TEACHING RESOURCES:

DEMOS
LABS
SIMULATIONS

- Hooke's Law
- Conservation of Energy in a Spring
- Pendulum investigations

LAB 9. Potential Energy Investigation: Spring and Gravitational
Objectives: To determine the spring constant of the spring, an evaluation of the extent to which the change in gravitational potential energy of the mass is equal to the change in the spring potential energy.
Equipment: Hooke's law apparatus, a set of masses and a meterstick.
Type of Lab: Open ended

LECTURE NOTES

- Simple Harmonic Motion

KEY ITEMS:

• It is important to keep the mathematical representation of simple harmonic motion connected to graphical representations and to demonstrations of real oscillating systems such as mass on spring and the simple pendulum.

• Help students identify where the maximum and minimum acceleration and
velocity occur as well as the energy changes.
