## 概述

Interactive collision simulation demonstrating momentum conservation and energy transformation in 1D and 2D collisions. Features momentum conservation: m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂', restitution coefficient: e = (v₂' - v₁')/(v₁ - v₂), where elastic (e=1), partially inelastic (0<e<1), and perfectly inelastic (e=0). Adjustable parameters: two masses (m₁, m₂), two initial velocities (v₁, v₂), coefficient of restitution e (0-1), impact angle for 2D mode, simulation speed, and slow-motion replay for collision moment. Visual displays include real-time 1D or 2D collision animation with velocity vectors, energy comparison bar chart (before/after/lost), momentum vs time chart, and velocity vs time chart. Toggle between 1D linear collision and 2D billiard-style collision with adjustable impact angle. Slow motion feature allows detailed observation of collision instant. Multi-language support (zh, en, es, fr, de, ru, pt).
