Newton's Mine teaches basic physics concepts through a series of puzzles in a realistic, 3D environment. Concepts are demonstrated qualitatively with no numbers or formulae. Each level focuses on a single concept and the relevant variables: the simple pendulum, momentum and collisions, the inclined plane, projectile motion, loops, and pulleys. Newton's Mine can be used as a curriculum supplement or in a home-school setting as an introduction to physics concepts at the middle-school level.
