Centre of mass of a system and of a rigid body
Place point masses and see the centre of mass; throw a body of unusual shape and watch the CM follow a parabola while the body spins; explode a projectile and see the CM path unchanged.

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.
