Animations don't have to run at a constant speed. You can use the Easing Type setting to vary the speed of an animation, making it speed up or slow down as it runs. Options include:
- Ease In: The animation begins slowly and then gets quicker as the animation progresses.
- Ease Out: The animation begins quickly and then slows down as the animation progresses.
- Ease Both: The animation begins slowly, moves faster in the middle, and then slows down again at the end.
- Linear: The animation moves at the same rate from beginning to end.
- Sine Wave: The animation moves in a cycle from beginning to end and back, slowing down slightly at each end of the cycle. For this easing type, the animation's "duration" property defines the time to complete one cycle from beginning to end and back.
