Damped and forced oscillations: resonance
A driven, damped spring-mass: transients die out and the motion locks to the drive. Sweep the drive frequency and see the resonance peak, phase flip and the effect of damping (Q factor).

What you do in the lab
Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.
Topics: forced oscillation · damped oscillation · resonance · Q factor · amplitude response
