Quick Answer: Anti Gravity Cone is a mechanics demonstration in which a double cone placed on a diverging inclined track appears to roll upward, while its centre of gravity actually moves downward. It is operated by hand and needs no electricity.
Last updated: October 2026
Key Features
Double cone with a specially designed inclined rail arrangement
Diverging rails make the cone seem to climb the slope
Shows that the centre of gravity falls even as the cone appears to rise
Manual operation on a stable, level surface
Covers centre of gravity, equilibrium and inclined plane behaviour
Part of the Physics Miscellaneous Products range, this apparatus is set on a level bench with the double cone at the lower end of the rails. Released gently, the cone appears to roll up the slope, and students then explain the motion in terms of its centre of gravity, which in fact moves downward.
Frequently Asked Questions
Q1. Does the cone really roll uphill? No. It only appears to move upward along the diverging inclined track, while its centre of gravity actually moves downward.
Q2. Does the Anti Gravity Cone need electricity? No. It is a manually operated apparatus used on a stable, level surface.
