1). Squash and stretch
This gives flexibility to objects. An example of squash and stretch is a rubber bouncing ball. The way the object squashes and stretches tells the viewer what material it is made of and how heavy it is.
Anticipation is the preparation for an action; if an object is about to travel in one direction it will momentarily move in the opposite. This movement builds momentum, and is something that is often seen in real life.
3). Slow in and slow out
Objects need time to accelerate and to slow down, like in real life. If this is not used, movements will look unnatural and robotic.
4). Follow through and overlapping action
Follow through is the idea that parts of an object keep moving after it has come to a stop. Overlapping action is similar, as it means that parts of the body may move at different times (e.g. when waving the shoulder may go up first).
Objects in real life use arcs when moving – if someone moved in a straight line it would look robotic.
