3A70.36 – Simple double pendulum
This demonstration shows chaotic motion using a double pendulum.

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.
1F20.10 – Inertia of Rest with Mass and String
This demonstration illustrates the inertia of rest of the mass, which changes depending whether the mass is jerked quickly or pulled slowly.
1C20.40 – Cart on Inclined Plane
This demonstration illustrates the inertia of fluid in a moving vehicle. When the cart stops, the liquid does not stop immediately.
1Q50.70 – Gyroscope
This demonstration illustrates conservation of angular momentum in a gyroscope.
1M40.41 – Ballistic Pendulum
This demonstration illustrates conservation of energy. The launcher stores potential energy, which is then converted to kinetic energy via the ball. The ball transfers this energy to the pendulum. By measuring the height reached by the pendulum, the potential energy can be calculated.
1D15.20 – High road low road
Although the total potential energy converted to kinetic energy is the same for each ball, the ball on the “low road” has a higher velocity for longer, and will thus reach the end first.
1N30.10 – Newton’s Cradle
This demonstration illustrates mechanical energy conservation in collisions. The number of balls that move is equal to the number of balls released, which shows the energy is conserved.
