The principle of animation that describes actions typically following an arched trajectory is known as arcs. This principle emphasizes the natural motion that many objects exhibit in the real world, where movements are not linear but instead follow a curved path. By implementing arcs in animation, creators can produce more fluid and believable movements, contributing to the overall realism and appeal of the animation.

Arcs give the audience a sense of fluidity and gracefulness, making actions like jumping or swinging appear more lifelike, as they mirror how objects behave under the influence of gravity and physics. This principle is essential for making animations visually engaging and easier for the audience to relate to and understand.
