The various weights of the rubber bouncing ball (top left), bowling ball (top right) and ping-pong ball (below, middle) create different reactions for each.

Lecture sketches showing the center of gravity in different shaped characters, and where the weight distribution is located above the various points of contact.

Note the subtle shift of the center gravity in this bottom-heavy ape character as it moves itself from its right foot to both feet.

As a consequence of all these factors, characters all move in their own ways. The lug will almost drag his body around, like the ape above, taking wide, slow, ponderous steps. There will be a great deal of slowing-in and slowing-out at the high position of his stride and he endeavors to first pull his weight up against gravity, then fight to control it as gravity pulls his body down again.

Of course, a regular character will have a more evenly balanced motion as it shifts its body mass from foot to foot, as on the left of the figure below. If the character was heavier or had a big belly or significant weight over the stomach area, the pose would have to be significantly modified, as on the right.

All action is relative to the nature of weight that a character or object has exerting itself upon them. Therefore, no two characters will move alike if their weight, structure, or need to interact with props they are carrying is in any way different.
