Formulas and Key Relations
2. SHM equations and parameters
x(t) = A cos(ωt + φ)
ω = 2π/T
ν = 1/T
v(t) = -ωA sin(ωt + φ)
a(t) = -ω²A cos(ωt + φ) = -ω²x(t)
3. SHM and uniform circular motion
y(t) = A sin(ωt + φ)
4. Energy in SHM
K = (1/2)mv²
U(x) = (1/2)kx²
E = (1/2)kA²
Frequency ν = 1/T.
Key relations
The SI unit is hertz, where 1 Hz = 1 s⁻¹.
