Slow in and Slow Out - Research

Slow in and slow out comes from the fact that certain movements need time to accelerate and decelerate, such as movements made by the human body and even inanimate objects such as bouncing balls.

Therefore the movement is slowed down by the use of more frames at the beginning and end of the action and less frames in the middle of the action.

I intend to find more examples of this and come up with my own but here are the initial examples I have found:
