A demonstration model of Newton's law of inertia that was studied in middle school physics classes, I miss the time in middle school.

It can be kept as a memento or given to friends, or placed on the desk at work or on the coffee table at home for decorative effect.

Material: Support and base > ABS plastic Ball > Iron

Five balls are suspended side by side, touching each other, and their centers are on the same straight line. First, pull the leftmost ball away by 15 to 20 mm, and then release it. When the ball next to it on the right collides, it stops, but the ball on the right swings up, and the distance of the swing is roughly the same as the distance the leftmost ball was pulled.

If the two balls on the left are pulled apart at the same time, after the collision, the two balls will stop. Meanwhile, there are two more balls on the right that start moving. When the right ball returns and collides with the left ball, it will transfer momentum to the left ball.

This is the law of conservation of momentum, but because of the Newton's law of inertia, such a collision will stop swinging due to the mutual cancellation of forces, so don't imagine it will swing forever!

This model is divided into three sizes, namely large, medium, and small. They are listed below with diagrams.

We offer custom orders with competitive prices for large quantities!

The principle of momentum conservation in physics, which I believe you are familiar with from high school. Playing with one, two, or three billiard balls, you see different effects, which is a lot of fun.Multiple play methods, it all depends on your imagination: (1) Use one ball to push the other four balls, and you will find that only one ball will swing back and forth; if you use two balls, both balls will naturally swing without the need for electricity, allowing the balls to be subjected to even pressure, making it a small craft for passing time when you are bored.

简介：动量守恒定律是物理学中的一个基本定律，它表明在没有外力作用的情况下，一个系统的总动量保持不变。动量是一个矢量，它表示物体运动的速度和方向。动量守恒定律通常适用于线性或旋转运动，并且它不依赖于物体的具体形状或质量分布。这个定律在物理学中有着广泛的应用，例如在分析火箭发射、汽车碰撞等问题时，都可以利用动量守恒定律来简化问题。
1. Definition: If a system is not subject to external forces or the sum of the forces acting on it is zero, then the total momentum of the system remains constant.

2. Applicable conditions: The system is not subject to external forces or the resultant force of the external forces acting on the system is zero, or the internal forces are much greater than the external forces.

Of course, there are more ways to play, which need to be DIY.
Multiple ways to play, relax and relax; Brain-boosting intelligence, fashion choice.
Placed in the study and as a gift, it shows personal rational art and refined sentiment.

In addition to the T-shaped and oval types.
