Squash and Stretch:
This is what gives the stop motion the weight because because its like a bouncing ball moving into a person walking, this is the important  element that you will need to do a stop motion.

Anticipation: This is a motion that is able to help you make the person move like jumping off the ground, running. so this motion is for helping your motion move.

Staging: this helps by getting different shots of the object you are taking pictures of like long, medium, or close up shots of the object.
