MOTION TWEENS: Motion tween is nothing but tweening a Symbol's movement from one position to another. 
TWEEN: "Tween" is actually short for "in-between", and refers to the creation of successive frames of animation between key frames.
KEYFRAME: A key frame in animation and filmmaking is a drawing that defines the starting and ending points of any smooth transition.
ANIMATION CYCLE: shows the cycle of the movement in different pictures displayed all at once to see the starting and ending point plus the in between parts.
