The twin trip, spacetime travel, time dilation, and length contraction are among the topics discussed. Static Electricity Planned for a Future Date. Current Electricity Planned for a Future Date. The nature of sound as a longitudinal, mechanical pressure wave is explained and the properties of sound are discussed. Wave principles of resonance and standing waves are applied in an effort to analyze the physics of musical instruments.
Color perception is discussed in detail.
The Physics Classroom began as a volunteer project during the 1996-97 school year. During the summer of 1998, a grant was received from The First in the World Consortium of Schools in order to complete some additional lessons on the topics of waves, sound, light, reflection and refraction. Thanks to the generosity and support of the Consortium, an additional five units were added to The Physics Classroom during the summer of 1998. At that time, fellow colleague Brian Wegley contributed a unit on Einstein's Theory of Special Relativity. Funds for the production of units on the topics of static and current electricity are presently being sought.
