Anti Gravity Cone

Product Code : SCL-AM-11157

Specifications

How the demonstration works

The cone is placed across the rails at their low, narrow end. The rails rise and spread apart towards the far end, and when the cone is released it rolls towards the raised end, which looks like motion against gravity. As the gap between the rails widens, the cone rests on its thinner sections nearer the tips, so its axis, and with it the centre of mass, drops lower between the rails.

Measured from the bench, the centre of mass falls while the cone travels 'uphill'. The demonstration reinforces a key idea of mechanics: a free body moves so as to lower its centre of gravity, and it is the path of the centre of mass, not of the contact points, that decides the motion.

1. Place the track on a level bench with the low, narrow end towards the class.
2. Set the cone across the rails at the low end and release it without pushing.
3. Let students watch the cone roll towards the raised end of the track.
4. Measure the height of the cone's axis above the bench at the start and at the end to show that the centre of mass has moved down.

Frequently asked questions

Does the anti gravity cone really roll uphill?

No. The contact points rise along the rails, but because the rails spread apart the cone sits lower between them, so its centre of mass moves down. Gravity acts as normal.

Which topics can be taught with the anti gravity cone?

Centre of gravity, stable equilibrium, rolling motion and the difference between the path of the contact points and the path of the centre of mass.
