The Newton pendulum is a desktop demonstration device invented in the 1960s. Five spheres of the same mass are fixed by hanging ropes and arranged closely to each other.Also known as: Newton's swing ball, momentum conserved swing ball, perpetual motion ball, physical billiards, bump ball, etc.The Newtonian pendulum was first proposed in 1676 by French physicist Edme Mariotte.When swing the rightmost ball and collide with the other four closely arranged balls when swinging back, the leftmost ball will be popped out and only the leftmost ball will be popped out.Of course, this process is also reversible. When the ball on the leftmost side of the swing hits other balls, the ball on the rightmost side will be popped out.When the two balls on the right most swing and hit the other balls at the same time, the two balls on the left most pops will be popped out.Similarly, the opposite direction is equally feasible and applies to more balls, three, four, five….Edit the principle of this section; the changes of five balls: the leftmost ball gets momentum and passes it to the ball hanging side by side on the right through collision, and the momentum is passed to the right among the four balls.When the ball on the far right cannot continue to pass momentum, it is popped up.This is a series of elastic collisions, which contain inelastic collisions and momentum.Since there is no other force in the collision, the l ball momentum of the left mass m velocity vl must be transmitted to the static ball on the right.The r-ball with the right mass m has the same momentum after being bumped.The hit balls all have a velocity vr to the right and have a tendency to move to the right, which is called conservation of momentum.The energy before and after the collision must be consistent, and the vibration movement of the ball is ignored here.

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!!

Wholesale description:

1. The total amount can be mixed with a total of 200 yuan!

2. A variety of styles of one product, allocated at the same time when shipping.

Freight description:

This sales center is located in Yiwu, Zhejiang, and is convenient for transportation.

1. Due to the consideration of reducing your freight costs and convenient customers, we generally recommend that you have a low shipping fee, transportation safety special line logistics, and the freight will be paid.Contact us to remove the freight)

2. The volume is not very large. Customers who are not very convenient for self -mentioning can use express transportation. When placing an order, the freight is set. Just take the payment directly.

After -sales service:

1. Please receive the number and quality of the baby in 3 days of checking the goods. If you have any problems, you can report it to the after -sales customer service in time.

2. Subjective dissatisfaction and imagination. In fact, the baby does not actually have a quality problem for returns and exchanges, and will not be accepted.

3 Because wholesale cannot be carefully checked one by one, quality problems are inevitable. The problems caused by transportation or quality. We will bear half of the shipping fee (in principle, the number is small, and the number of logistics is available.If you return more, it is relatively saving freight!
