Neon physics simulation interaction symbol collection

A set of twelve clean, modern icons depicting various physics, motion, and interaction concepts. The icons are rendered with a glass-like material, featuring a soft inner glow and a vibrant neon gradient palette shifting from ultraviolet purple to cyan blue. Each symbol is placed on a deep black background, which makes the luminous edges and semi-transparent surfaces pop with a high-tech, futuristic aesthetic. The icons cover themes like liquid splashing, gravitational impacts, object displacement, geometric arrangement, and circular motion. The lighting is uniform and soft, simulating a refractive, translucent material quality. These icons appear to be designed for a UI/UX library for gaming engines, simulation software, or creative motion tools, focusing on abstract representation of mechanical behaviors and spatial dynamics.
