I'm a teacher at a Senior High School in Indonesia. I have two Senior High School physics books (Indonesian book) written about simple harmonic motion formula:
But I have another book, a university student physics book (International book), written:
Are there some things wrong with my Indonesian Senior High School books? Or maybe the writers have a purpose that I haven't known yet? Thanks.
y = A sin θ = A sin (ωt + θ0) = A sin 2πφ = A sin 2π (t/T + θ0/2π)
phase angle = θ = ωt + θ0
phase of wave = φ = t/T + θ0/2π
phase angle = θ = ωt + θ0
phase of wave = φ = t/T + θ0/2π
But I have another book, a university student physics book (International book), written:
y = A sin (ωt + φ)
phase angle = phase of wave = φ
phase angle = phase of wave = φ
