A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc2.
B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion.
C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy.
D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields.
E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer. Students can vary friction and the strength of gravity.
- Design experiments to describe how variables affect the motion of a pendulum
- Use a photogate timer to determine quantitatively how the period of a pendulum depends on the variables you described
- Determine the gravitational acceleration of planet X
- Explain the conservation of Mechanical energy concept using kinetic energy and gravitational potential energy
- Describe energy chart from position or selected speeds
