Vertical Impulse Device

This device demonstrates two fundamental laws of mechanics — the conservation of energy and the conservation of momentum. Three metal spheres of different sizes and masses are suspended vertically. When the top sphere is set in motion, its energy and momentum are transferred in a chain reaction to the spheres below. The difference in mass affects the speed and amount of energy transferred.

This process is an excellent example of the combined effect of elastic collisions and gravitational force. During motion, part of the mechanical energy is converted into heat and sound, but the majority is preserved as kinetic energy. The device is commonly used in physics classes as an experimental tool. Through simple observation, people can grasp complex physical concepts.

Only a small initial input of energy is needed to start the motion. The rest is governed by the laws of nature. Every swing and collision in this setup is a vivid demonstration of invisible but unchanging physical laws.

As the spheres are released from above, potential energy is converted into kinetic energy as they fall. When a sphere collides with others, momentum conservation and energy transformation can be observed. Due to differences in mass and size, variations in motion and speed become clearly visible.

The principles of energy and momentum conservation were scientifically established in the 17th century through the work of Isaac Newton. The first pendulum experiments were conducted in the early 1600s by Galileo Galilei. Devices demonstrating energy transfer between different masses became popular in the 19th century in education and science exhibitions. Today, this device is recognized both as an educational tool and a symbol of the beauty of physics.
