What animation principle dictates that parts of a character continue to move even after the main body has stopped?

The principle that dictates that parts of a character continue to move even after the main body has stopped is known as Follow Through. This animation technique creates a sense of realism and adds a dynamic quality to movement, making animations feel more fluid and natural.

When a character comes to a halt, different parts of the body do not stop moving instantaneously; instead, they often continue moving for a moment due to inertia. For example, if a character were to stop running, their hair, clothing, or limbs may continue to sway or bounce slightly after the main action has ceased. This follow through adds depth to animations, making actions appear more lifelike and visually engaging.

By incorporating follow through, animators can emphasize the weight and physicality of characters, ultimately enhancing the viewer's experience. This principle is crucial in character animation, as failure to include it can result in stiff and unnatural movements that detract from the overall effectiveness of the performance.
