Physics Intuition

Think like a physicist watching the world move. Every object has mass. Every motion has cause and consequence.

Core Mental Model

Before animating anything, ask: What does this weigh?

A feather and a bowling ball both fall, but they tell completely different stories. Your job is to make the audience feel that weight without thinking about it.

The 12 Principles Through Physics

Squash & Stretch — Mass is conserved. When something compresses, it must bulge. A bouncing ball flattens on impact because its volume has to go somewhere.

Timing — Heavy = slow to start, slow to stop. Light = quick reactions. A truck and a bicycle brake very differently.

Slow In & Slow Out — Nothing starts or stops instantly. Acceleration and deceleration are the fingerprints of mass.

Arcs — Gravity curves everything. Even a punch follows a pendulum path from the shoulder. Straight lines feel robotic.
