## 概述

Interactive simulation of sliding friction with comprehensive static and kinetic friction analysis. Features physics formulas: static friction f_s ≤ μs·N (matches applied force until maximum), kinetic friction f_k = μk·N (constant when moving), normal force N = mg·cosθ, maximum static friction f_s,max = μs·N, and motion condition F > μs·mg·cosθ. Demonstrates stick-slip behavior with μs > μk relationship. Real-time visualization shows block on horizontal/inclined plane with force vectors (gravity mg: red downward, normal N: green perpendicular to surface, friction f: orange opposing motion, applied force F: purple in direction of push). Interactive f vs F graph showing three phases: static region (linear increase f = F), transition point (F = f_s,max), and kinetic region (constant f = f_k < f_s,max). Current operating point displayed with red dot on graph. Adjustable parameters: mass m (1-20 kg), static friction coefficient μs (0.1-1.0), kinetic friction coefficient μk (0.05-0.9), applied force F (0-100 N), gravity g (1.6-20 m/s²), and plane angle θ (0-45°). Real-time displays: friction force, normal force, applied force, state (static/kinetic), and motion indicator. Force display toggles for each vector. Educational content covering static friction principles, kinetic friction behavior, comparison of μs vs μk, stick-slip phenomenon, and real-world applications (brakes, tires, conveyor belts, mechanical systems). Multi-language support (zh, en, fr, de, es, pt, ru).
