如何计算Simple Harmonic Motion
learn.whatIsHeading
Simple harmonic motion (SHM) describes oscillatory motion where acceleration is proportional to displacement and opposite in direction. Springs and pendulums exhibit SHM.
公式
x(t) = A × cos(ωt + φ); v = -Aω × sin(ωt + φ); a = -Aω² × cos(ωt + φ)
分步指南
- 1Enter amplitude A, angular frequency ω, initial phase φ
- 2Calculate position, velocity, and acceleration at time t
- 3Analyze period T = 2π/ω
例题解析
输入
A = 0.5 m, ω = 2 rad/s, t = 0.5 s
结果
x ≈ 0.24 m, v ≈ -0.87 m/s
