Push the cart and eject the steel ball from the spring-loaded barrel. The ball falls back into the barrel of the moving car, demonstrating that the forward motion of the ball is the same as the vehicle from which it was ejected. Comes with a steel ball, release pin and cord. The barrel permits two different heights of ball flight.

When is a bicycle wheel a gyroscope? When you put a new "spin" on it. Give our bicycle wheel a spin, then try to tilt or deflect it. Our student-sized bicycle wheel turns freely on its axis and has large, comfortable handles at each end. Because mass is concentrated at the rim, you can tilt the spinning wheel to feel the force of rotation. With instructions.

Useful for demonstrating momentum, conservation of energy and torque! The unit is suspended by two strong cords, which are wound around the shaft of the wheel and then released. The wheel will unwind as it falls but will wind itself back up as the momentum carries the wheel upward in the opposite direction. This oscillation process will continue for several moments as the wheel slowly loses momentum and travels less each time. Instructions included.

This robustly constructed inertia demonstrator works reliably every time and is a great improvement on traditional versions of this classic experiment. A steel ball rests on a thin metal card on top of a pillar, and a spring-loaded catch is mounted next to the pillar. When the catch is released, a piston strikes the edge of the metal card sharply. The card flies out from under the ball, which remains in place on top of the pillar due to its large inertial mass. The card is tethered to the aluminum base for easy recovery after the experiment.

The design of the Spillnot uses the principles of Newtonian physics to keep the liquid in the container. The flexible handle and location of the suspension point above the center of the tray ensure that the forces on the liquid are always directed toward the supporting tray, even when the tray is in motion. Sideways forces usually responsible for spills are not transmitted to the tray by the flexible handle. Radial forces generated during swinging motion only force the liquid into the container more firmly. An inexpensive demonstration to intrigue students and challenge their analytical powers! Includes activity guide. 5" x 5" x 9". Weight: .25 lbs.
