An Air Track is a scientific device accustomed to study motion in very low friction surroundings. Its name comes type its structure: air is tense through a hollow track with fine holes right along the track that permits specially fitted air track cars to glide comparatively friction-free. Air tracks are typically sq. in cross-sectional. Carts match nearly onto the highest of the track ar accustomed study Linear motion in low friction environments.
