Newton's Second Law of Motion algorithm is crucial to interactive visual effects and interactive behavior in interface design. Designers can only utilize simple algorithm templates in interface design since they lack organized mathematical science, especially programming. Directly using Newton's Second Law of Motion algorithm introduces two interface design issues. First, the created picture has a simplistic impact, laborious interaction, too few interactive parts, and boring visual effects. Second, using this novel approach directly to interface design reduces creativity, originality, and cognitive inertia. This study suggests a Newton's Second Law–based algorithm modification. It provides a novel algorithm application idea and a design strategy based on algorithm change to enable new interface design. Algorithm design gives interface design a new viewpoint and improves content production. In the arithmetic process of Newton's Second Law of Motion algorithm, the introduction of repulsive force, reset force, shape, color, and other attributes of interactive objects, and the integration of other algorithms to transform its basic arithmetic logic, is conducive to the improvement of the visual effect of interaction design. It also improves users’ interaction experiences, sentiments, and desire to participate with design work.
