What Physical Science covers
- Energy, motion and forces (P.a, P.b): heat transfer, energy types and sources, waves, speed and acceleration, momentum, Newton’s laws, work, machines and power.
- Matter and chemical reactions (P.a.2, P.c): atoms, physical and chemical changes, density, states of matter, balancing equations, conservation of mass and solutions.
Codes are GED Testing Service’s assessment targets and content topics from its Assessment Guide for Educators; the topic groupings and summaries are ours.
