1J20.70 – Rolling uphill [double cone]

This demonstration utilizes a double cone on a specifically designed ramp to illustrate the importance of the center of mass in determining the rolling direction. The track’s geometry creates an incline, but the double cone’s wider section reaches under the top of the rails as it rolls. Hence, lowering its center of mass despite the ramp’s slope and minimizing the system’s gravitational potential energy.

1Q10.30 – Cylinders on an inclined plane

This demonstration involves cylinders of various densities rolling down an inclined plane. It illustrates the principles of gravity, friction, and inertia in a tangible and engaging way.

1G10.42 – Atwood’s machine

Atwood’s machine consists of two weights connected by a string that passes over a pulley. The demonstration shows how the machine can be used to study the laws of motion and gravity, different weights lead to different results.. It’s a practical and visual way to understand Newton’s second law of motion and the concept of gravitational acceleration.

1M20.11 – Pulleys

This demonstration illustrates how a balance of forces can be achieved using a pulley system.
