Features:
This desktop display model is a version of Newton's cradle, a device that demonstrates the conservation of momentum and energy through a series of swinging spheres of the same size.
Newton's cradle has been around for a long time, and it is still a symbol of the scientific community today because it simply demonstrates an important law in physics.
The device demonstrates the conservation of Newton's momentum and energy through a series of swinging spheres of the same size. When one ball at the end is lifted and released, the force generated crosses the line and pushes the last ball outward.
Put it on your work desk and take a break from a stressful day by watching this soothing and attractive sculpture display.
This can also be used anywhere in your home; the placement of this piece can create a tranquil atmosphere almost anywhere!
