Physics & Mechanics

Physics explains how matter, forces, motion, and energy behave. For General Science, focus on forces, mass and weight, gravity, Newton's laws, friction, momentum, energy, machines, pressure, buoyancy, sound, and basic light behavior. This is a conceptual lesson, not a calculation-heavy physics course.
