What are 20 types of motion?

While there are countless specific motion examples, they generally fall under these categories: rectilinear (straight line), curvilinear (curved path), circular, rotational, oscillatory, vibratory, periodic, non-periodic, uniform (constant velocity), non-uniform (changing velocity), translational, projectile, spinning, rolling, sliding, free fall, parabolic, elliptical, hyperbolic, and helical motion. Most real-world motions combine several of these types.
