Animation is not just about moving things around; it's also about creating a sense of realism, consistency, and naturalness. To achieve this, you need to pay attention to the timing, easing, spacing, staging, anticipation, follow-through, squash and stretch, arcs, secondary action, and appeal of the animation. These principles can help you create smooth and expressive animations that will delight users. Timing determines the speed of the animation while easing controls how it accelerates or decelerates. Spacing is how the animation covers the distance; staging is how it is positioned and framed; anticipation is how it prepares for the next action; follow-through is how it completes the action; squash and stretch is how it changes shape to show weight and elasticity; arcs are how it follows a curved path; secondary action adds detail or variation; and appeal makes the animation pleasing and engaging.
