Newton is a desktop demonstration device invented in the 1960s. The five -quality spheres are fixed by the camisole and arranged closely with each other.Also called: Newton's ball, constant kinetic ball, permanent ball, physical collision, touching the ball, etc.Newton is a French physicist Isam·Edme Mariotte was first proposed in 1676.When the ball on the far right side is swinging and the other four balls that are tightly arranged during the return, the leftmost ball will be popped up, and only the leftmost ball will be popped up.Of course, this process is also reversed. When the leftmost ball hit the other balls, the right of the right side will be popped up.When the two goals on the right side swing at the same time and hit the other balls at the same time, the two left on the left will be popped up.In the same way, the direction is also feasible, and it is suitable for more balls, three, four, five……EssenceEdit in principle of this paragraph; change of five balls: The leftmost ball gets the momentum and passed to the ball hanging on the right side by collision, and the momentum is passed to the right among the four goals.When the ball on the far right cannot be passed on, it is popped up.This is a series of elastic collisions, which contains non -flexible collisions and momentum.Because there is no other force in the collision, the volume of the L -ball Motor of the Mass M Speed ​​VL on the left must be passed to the static ball on the right side.The R -ball on the right quality m has the same momentum after the collision of the R -ball.The collision balls have a speed of VR to the right and moving to the right, which is called constant momentum.The energy before and after the collision must be consistent. Here I ignore the vibration movement of the ball.

Newton's ball is a classic decorative toy in Europe and the United States, and it is also a very beautiful scientific toy. It can reflect the law of the physical law discovered by the great physicist Newton, the law of constant kinetic energy. You just need to pull the outer steel ball, and then put it.Open, the opposite steel balls will play up, and then it will bounce dozens of times until the power disappears and stops. Therefore, the higher the steel ball you pull, the greater the strength, the more you can play.The smaller the power, the less the number of bombs, the very interesting. This kind of crafts full of intelligence and art are definitely the best choice you put on the desk. When boredIt will make you go to work more powerful.

A demonstration model of Newton's law of inertia learned in middle school physics class. I miss my time in middle school. It can be kept as a souvenir or given to a friend, or placed on the desk to decorate the coffee table at home. Five balls are hung side by side, and they are in contact with each other and the center of the ball is on the same line. First, pull the ball on the left 15 to 20MM apart, then let it go, and the ball on the right collided and stops, while the ball on the right is swinging, and the distance of the swing is roughly the same as the distance of the ball on the left.If the two balls on the left are pulled apart at the same time, then the two balls will stop after the collision, and two balls on the right swing. When the ball swings back and collides with the ball on the left, the momentum will be passed to the ball on the left.This is the law of conservation of momentum. But because of Newton's law of inertia, this mutual collision will eventually stop swinging due to the mutual cancellation of forces, so don't imagine that it will swing all the time!When lifting a ball from the side with your hands, release your hand when you lift a ball from the side with the maximum diameter point horizontal to the other 4 balls (lift two or three balls, see different effects, and enjoyable. There are many ways to play, and look at your relatives’ imagination). You will find that only 1 ball will swing back and forth; if it is 2 balls, the two balls will naturally swing without electricity to make the ball swing evenly under force. This is a small process to pass the time when you are bored.In addition, a function derived is that when you are unable to fall asleep for a long time, will you feel pain?When you count sheep one by one, do you feel that you are too naive?Then please try this, stick it on the table, move your eyes as the iron ball collides, and you will fall asleep peacefully without long!!!While playing, don’t forget another feedback it brings, that is, education and entertainment.The law of conservation of momentum definition: If a system is not subjected to external forces or the sum of external forces it is subjected to is zero, then the total momentum of this system remains unchanged.I would like to remind you here. It is precisely because this is the law of conservation of momentum. When the spheres collide with each other, the ball will slowly stop swinging due to air resistance. Please do not believe what the market says can swing forever. That is unrealistic. If inertial swing is to achieve eternity, it will be possible to achieve it in a specific environment!!
