Motion, Tweening and Easing

Three key components of a motion

1. Position  2. Time  3. Beginning Position

 

Key components of a Tweenis

1. Duration  2. Final position

 

Position and time have this one-to-one relationship.

 

Position is a function of time.

p = f(t)

 

Easing is acceleration, a change is speed.

1. Ease-In : start slow and speed up

2. Ease-Out : start fast and speed down

3. Ease-In-Out : The first half of the tween is an ease-in, the second half, an east-out
