My dear friends, how are you? I hope you are all well, and your moments be full of hope and motivation. Please enjoy every moment of your life deeply.
As usual, always first let me thank my dear supporters for their constant support. You don't know how much your existence always warms my heart. Thank you for your kind presence, my dears...
Yesterday the birthday was very good, and we had a great time, I remembered all of you. I will definitely talk about the party in a little article tomorrow, but today I preferred to talk to you a little about Newton's cradle, the gift I got yesterday for my cousin. Because you all liked this gift so much, and it was interesting to you, I said to myself, I must write a little about it today. Yesterday I used the translation of what we call it in our language, "the Newton's sphere", but today, when I searched for its scientific name, its scientific name in English is the same as "Newton's cradle".
Newton's cradle consists of a number of oscillating spheres. It actually consists of five metal spheres hung with thin wires from a frame, arranged so that they have only slight contact with each other.
When you lift one of the end balls and pull it out and then release it, when it hits the next ball, it is completely fixed, and only the last ball in the opposite row is thrown up. And then when it returns to its place, and hits the other balls, it is fixed again, and only the last ball in the opposite direction is thrown out again. And this reaction continues in a chain, until it finally stops.
The work of this device can be explained by some basic principles of physics and mechanics, which were discovered by scientists such as Isaac Newton and René Descartes.
Newton's cradle cleverly demonstrates the principle of momentum conservation in physics. When the first sphere in Newton's cradle hits the second sphere, the first sphere stops, but its momentum doesn't disappear. And is transferred to the second, third, and fourth spheres, as they are fixed. Until it reaches the last ball, and finally throws the last ball up. And it has an impulse almost similar to the impulse of the first sphere.
Now if we pull two balls from one end of the cradle up, and release them, two balls will be thrown up at the opposite end. And these two spheres at both ends will oscillate until they are finally fixed.
This continuity of oscillations implies another Newton's principle called the "energy conservation principle". This principle states that energy is neither created nor destroyed, but transformed from one form to another.
In fact, Newton's cradle shows how potential energy is transferred in the second, third, and fourth fixed spheres, eventually reaching the fifth sphere, causing the end sphere to be thrown upward.
Some believe that Newton's cradles also have anti-stress properties. In Feng Shui science, Newton's cradles are sometimes used on the desk to reduce workplace stress. Not only does it make your work environment and desk look beautiful, but in the midst of the hustle and bustle of work, it helps to take a moment off from your daily routine, and is meditative.
Newton's cradles can also be good and new options for giving as a gift to your friends, which you can buy in different sizes and designs. By the way, they are also reasonably priced, and the smallest size in my area starts at around $3... 😉
This is really interesting and physics never disappoint when it comes to entertain us with knowledge. This is really a perfect gift for those who loves physics , I will try to find one as I already fell in love with this.
