Rolling without slipping: ring, disc and sphere race
Race a ring, hollow sphere, disc, solid sphere and a frictionless block down an incline. See how moment of inertia decides acceleration a = g sinθ/(1 + I/mR²), and what happens when friction is too low to roll.

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.
