Example Concept: Easing curves, such as linear, ease-in, ease-out, and ease-in-out, modify the rate of change in an animation's motion. Linear easing maintains a constant speed, while ease-in starts slow and accelerates, ease-out begins fast and decelerates, and ease-in-out combines both for a smooth start and finish. These variations help convey different emotions and physical properties, like weight and tension, enhancing the animation's storytelling and visual appeal.
