Como usar (3 passos)
- Choose Spring or Pendulum and keep the sample values or enter your own.
- For the spring, enter mass m, spring constant k, amplitude A, and optional time t. For the pendulum, enter length L, gravity g, and an amplitude angle (Earth and Moon presets are one tap).
- Press Calcular to view ω, period, frequency, peak speed/acceleration/energy, and a step-by-step breakdown for each mode.
Key formulas: spring ω = √(k/m); pendulum ω = √(g/L) (small-angle approximation).

FAQ
What is simple harmonic motion?
Simple harmonic motion is a repeating oscillation where the restoring force is proportional to displacement. Mass–spring systems and small-angle pendulums are classic examples.
Does pendulum period change with amplitude?
In the small-angle approximation used here, the period is nearly independent of amplitude. Large swings deviate and the actual period becomes slightly longer.
How do mass and spring constant affect the period?
For a spring–mass system, T = 2π√(m/k). Heavier masses oscillate more slowly, and stiffer springs (larger k) oscillate faster.
