What is physically based animation? How is it different from the traditional animation?

Traditional animation usually involves an artist in the loop. Artists must (often painstakingly) animate the way CG human characters walk, move, dance, emote, etc., for CG movies like those created by Pixar. On the other hand, physically-based animation involves defining a specific set of physical rules (e.g., a description of how particles collide and bounce off each other) to compute animations, and is used for simulating fluids, gasses, particles, hair, and so on. Also, I should note that these two areas can also interact: this includes giving a user artistic control over smoke animations, or optimizing physics-based walking controllers to have a human character walk naturally along a user-defined path.
