Formula and example
How it is calculated
ω = √(k/m); T = 2π/ω; E = ½kA²; vₘₐₓ = ωA
Worked example
With k = 100 N/m, m = 1 kg and A = 5 cm, T is approximately 0.6283 s and the energy is 0.125 J.
Things to check
- The amplitude is converted from centimetres to metres.
- The model uses a linear spring and constant mass. Friction and damping are excluded.
