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 inertial law learned in the middle school physics class, I miss the time of middle school; can be reserved as a commemorative or presented to friends, or decorative effects on the coffee table on the desk;In the same line of contact with each other, the ball is on the same line. First, the ball on the left is opened for 15 ~ 20mm, and then let it go.And the distance between the swing is roughly the same as the distance between the ball on the left.If the two balls on the left are opened at the same time, then the two balls stopped after the collision, and there were two balls on the right. When the right ball swing back and collided with the left ball, it would be again.Pass the momentum to the ball on the left.This is the law of constant momentum but because of the law of Newton's inertia. This kind of collision will eventually stop swinging due to the mutual offset of each other, so don't imagine it will continue to swing!Make a ball from the side to the maximum level at the side at the side of the other four goals.) You will find that there is only one club to swing back and forth; if it is 2 balls, 2 balls naturally swing naturally without electricity to make the ball be swinging evenly.Process.In addition, a function derived is that when you can't fall asleep, will you feel pain?When you only count the sheep, do you feel too naive?Then use this to try, pick it on the table, and move your eyeball with the collision of the iron ball. You will sleep safely without a long time!IntersectionIntersectionDon't forget to play while playing, that is, it is entertaining.The definition of the law of constant momentum: If a system is not subject to external force or the sum of external forces is zero, the total amount of motion of this system remains unchanged.Here we should also warmly remind you that the proximity of the sphere that this paragraph is the law of constant dynamics and conservation is affected by air resistance in the process of collision with each other.If you want to achieve eternity, it is possible to achieve it in a specific environment!Intersection
