Position, velocity, and acceleration: the three numbers that describe any moving thing, and the graphs that tell their story.
Describing Motion
Position, velocity, and acceleration: the three numbers that describe any moving thing, and the graphs that tell their story.
Forces and Newton's Laws
Force as a push or pull, the three laws that connect force to motion, and the free-body diagram that turns a problem into arrows.
Work, Energy, and Power
Work, kinetic and potential energy, conservation, and power, the rate of doing it.
Waves and Sound
Waves carry energy without carrying material: wavelength, frequency, speed, and what your ear actually hears.
Electricity and Magnetism
Charge, fields, and the two-way marriage of electricity and magnetism that runs every motor and generator.
