• Animators call “drag” the effect seen when a soft material, such as hair, flesh, or cloth, trails behind the rest of the motion of the character.
• Drag and follow-through are explained by inertia: anything that’s not moving will remain at rest and anything that is moving continues moving until acted on by an unbalanced force.
• The apparent outward pull that we attribute to centrifugal force is also due to inertia since objects move uniformly in a straight line until acted on by an unbalanced force.
