Did you know that the apparent scale of an object in your animation is directly related to its timing? Check out Alejandro Garcia’s post at Animator Island that discusses the relationship between these two important animation concepts.
Physics for Animators also includes an entire section on Motion and Timing. The book covers a number of different animation scenarios such as falling or slowing down due to friction, and shows how to easily calculate the distance an object should move in order to jive with real-world physics.
