6 slow in slow out

Movement needs time to accelerate. It starts slower and speeds up, like a car. You can’t go 0km per hour to 120 in no time flat!  But the car also needs to slow before it comes to a stop. Most things work this way, including the human body so this is important to keep in mind.

To make this effect occur you put more drawings in the beginning and end of the action and less in the middle.
