: Most natural actions (like an arm swinging) follow a circular path rather than a straight line. : Determines how fast an action occurs and
: Gives a sense of weight and flexibility to objects (e.g., a ball flattening as it hits the ground). : Gradual acceleration and deceleration to make motion
: Gradual acceleration and deceleration to make motion look organic rather than mechanical. The fundamentals of animation in Web Design
