This demonstration illustrates the influence of the spring constant, amplitude of the oscillation, and the mass of the cart on the period of oscillation of the one/two cart system.
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 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
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 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…
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 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 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 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…
