Class 11 Physics simulations · Oscillations

Driven oscillations and resonance

Drive a damped oscillator near its natural frequency and watch its steady-state response build in amplitude.

Open the simulation

What to notice

The response peaks near the natural frequency. Damping limits the peak and changes the phase lag.

Key relation

A = F₀/√[(k−mω²)²+(bω)²]

Try this

Compare driving at 0.5 Hz and close to the 1.0 Hz natural frequency.

What you can change

• Driving frequency: 0.25 to 1.75 Hz
• Damping coefficient: 0.5 to 3.5 kg/s
• Driving force amplitude: 0.5 to 3 N
