Elastic Energy and Wave Motion








Would you like two great experiments for teaching the Elastic Energy section of grade 12 physics (SPH4U) and the Waves unit of grade 11 physics (SPH3U)?

Computer technology (web camera, video analysis software) used in both the experiments enhances the level of learning for the students. Students are able to visualize the simple harmonic motion as a sine wave and derive the time period, spring constant, etc.

The grade 12 experiment allows your students to find the spring constant of the spring and prove the conservation of energy principle.
