Introduction to Physics
Chapter 1: Motion and Forces
Newton's laws describe the relationship between a body and the forces acting on it, and its
motion in response to those forces.
Chapter 2: Energy
Energy exists in various forms, including kinetic and potential energy, and it is conserved in
isolated systems.
Chapter 3: Waves and Sound
Waves transfer energy without the transfer of matter, and sound is a mechanical wave that
travels through a medium.
