If an element is selected with an existing animation, you can further adjust the animation using the highlighted button. Easing options make the animations feel more natural

Linear (Standard)

Linear animations often feel unnatural, which is why it is not the best option most of the time.

Ease In

Animations with ease in begin slow and end fast.
A stone that falls to the Earth from a great height behaves according to this pattern

Ease Out

Animations with ease out begin quicker and become slower by the end.
Ease out is often used in interface
design, since the quick start creates a feeling of “responsiveness”.

Ease In Out

Animations with ease in out begin slow, are quick in the middle, and end slowly, like an automobile that accelerates and afterwards brakes again.
