Quick Answer: The Anti Gravity Cone is a mechanics demonstration model in which a double cone appears to roll uphill on a diverging track while its centre of gravity actually moves downward.
Last updated: October 2026
Key Features
Includes 1 double cone and 1 inclined diverging track or rail assembly.
Shows that the cone moves in the direction where its centre of gravity becomes lower.
Creates a rolling uphill effect for classroom explanation.
Helps explain how shape, rail angle and support width affect motion.
Needs no electricity, battery or external power.
About This Product
The track is set on a level bench with its two rails diverging outward, and the double cone is placed at the narrow lower end and released gently. As the rails widen, the cone seems to climb. Students compare this apparent motion with the actual movement of the centre of mass, a memorable way to teach centre of gravity, stable equilibrium, rotational motion and potential energy.
Frequently Asked Questions
Q1. Why does the cone seem to roll uphill? As the cone rolls toward the wider end of the diverging rails, its centre of gravity lowers. The cone moves in the direction where its centre of gravity becomes lower, even though it appears to climb.
