As an animator, you have to control how motions look and feel.
Theat means you need to do more than just somehow moving things around. The most powerful tool that you have to control how a motion feels is spacing.
Spacing is the distance an element travels between two frames of an animation.
Small spacing = small movement
Big spacing = big movement
By increasing and decreasing the spacings over the course of multiple frames, easing can be added to a motion.
A motion with the same spacing between each frame is called a linear motion. This only occurs very rarely in nature and usually needs to be avoided.
