This demonstration illustrates the inertia of fluid in a moving vehicle. When the cart stops, the liquid does not stop immediately.

This demonstration illustrates how the ball has no “memory” of its initial direction of travel. We see the movement of the ball as it leaves the roller is perpendicular to…

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…

This demonstration illustrates the deformation of a surface under rotation to equalise pressure.

This demonstration illustrates projectile motion. Specifically, it describes how a projectile launched vertically with a certain horizontal velocity will keep said velocity and describe a parabola in its flight

This demonstration illustrates the inertia of rest of the mass, which changes depending whether the mass is jerked quickly or pulled slowly.

This demonstration illustrates forces and is a good way to show a counterintuitive (if not fully understood) phenomenon.

Although the force generated by the fan is constant, the track and wheels restrict the movement, and thus the component of force in the direction of movement is proportional to…

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…

This demonstration illustrates how the centre of mass of an irregular shape can be found.

This demonstration shows how the forces are balanced, as the Newton meter should stay stationary as the masses are increased, and should show the sum of the forces created by…

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

This demonstration illustrates energy conservation in an object undergoing rotation, as well as centripetal force. The forces and energy types involved are (translational and rotational) kinetic energy, (gravitational) potential energy…

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…

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.

This demonstration illustrates momentum transfer through solids via the velocity amplification of the upper ball as it is ejected.

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.

This demonstration shows the conservation of angular momentum, since the excess of momentum created by “reversing” the rotation of the wheel is transferred to the person on the stool.

This demonstration shows Gyroscopic precession, which is a phenomenon that arises when a torque is applied to a spinning wheel (in an axis other than the one the wheel is…

This demonstration illustrates conservation of angular momentum in a gyroscope.

This demonstration shows Hooke’s law, in this case for the extension of a spring. Knowing that the force applied to the spring is directly proportional to the extension caused by…

This demonstration shows chaotic motion using a double pendulum.
