Physics
Newton’s Cradle
The large model ball impact device is a classic Newton’s cradle, which clearly demonstrates Newton’s 3rd law of motion: that action and reaction are equal and opposite.
The device can also be used to demonstrate conservation of momentum when moving balls transfer their energy and momentum to the other balls in the system. The construction is robust, and the steel balls are suspended so that they can swing freely and precisely. The dimensions of the device are 245 x 148 x 224 mm, which provides a solid and visible model, suitable for classroom teaching.
Use of the product
In physics classes, the ball impact apparatus can be included in courses on mechanics, forces and motion. Students can observe how energy and momentum are conserved in elastic collisions, and how the number of balls set in motion affects the outcome. This provides a concrete basis for discussions about energy transfer, momentum and practical applications of Newton’s laws.
The device can also be used in other contexts, for example in technical education or in dissemination at science centers and museums, where it functions as a visual and easy-to-understand example of basic physical principles. In professional contexts, it can be used as a pedagogical tool in, for example, engineering or design processes where impulse and energy transfer play a role.
