NEWTON BALL PENDULUM Newton's Pendulum is an amazing gadget depicting the operation of the law of physics - the law of conservation of momentum and energy. When one ball is pulled back and released, its impact on the pozostałe balls will cause only the last ball to jump off on the opposite side of the series and the pozostałe will remain stationary. This is because the collisions of the balls are elastic and their kinetic energy and momentum are preserved. Similarly, when we pick up and release two balls, two balls will also jump off the other end. There are 5 steel balls hanging on the strings, which can only make fluctuations in one common plane. Specification: Material: Plastic base and steel balls Dimensions: approx. 9,5 x 9 x 7,5 cm Base color: black The set includes: 1 x Base 1 x balancing ball Newton's cradle is one of the favorite toys of all kinds of directors and CEOs. This gadget looks great on the desk and has calming properties. So how? First of all, we use the available materials and give im a second life, regardless of tego, of which they are made. We rely on cartons from the so-called. second hand, which we receive from our suppliers. Za filling, we usually use pieces of cardboard and more delicate, especially glass items tightly wrap with corrugated cardboard, newspaper or available plastic. Reused plastic is more eco-friendly than freshly produced cardboard. Therefore, do not be surprised if you see plastic elements in the package - most often they come one from our suppliers, who also use them again. Sometimes we take some plastic and cardboard boxes from friends and family so they don’t go to waste. Ty can also try using your package and fillers again!
