What Actually Happens If You Shoot a Ball at a Newton’s Cradle?

Therefore, the following obvious question is: Is kinetic energy stored, just as energy is stored? The answer is: sometimes. At what we call the “force pulse,” both kinetic forces and speeds are retained. Often, a collision occurs between the larger objects – such as two rubber balls, or water balls that collide. If we have a strong pulse in one phase (meaning that everything happens directly), then we have two equations we can use: energy conservation and kinetic energy conservation.

In addition to the elastic, there are two types of collisions. When two things collide with a stick, like the clay that strikes a log, then the collision is complete. In that case, the speed is still maintained and we also know that the final speed of the two objects is the same, because they stick together.

Finally, there is the issue of how two things clash but do not connect and do not store kinetic energy. We simply refer to it as “collision,” since it is not one of two distinct phenomena (stretching and immovable). But keep in mind that in both cases, the speed is maintained as long as the collision is short-lived.

Well, now let’s consider a problem that is a major part of Newton’s baby. Suppose I have two identical steel balls (m), ball A and ball B. Ball B starts to breathe, and ball A moves in the same direction. (Let us mention v₁.)

Before the collision, all the power would be mv₁ + mx0 = mv₁ (since ball B starts to breathe). After a collision, all power must remain mv₁. This means that all the balls can move at a speed of 0.5v₁ or other combinations — as long as the total energy is mv₁.

But there is another obstacle. Since it is a strong hit, kinetic force is a must too stored. You can do the math (not too hard), but it seems that to keep all of the KE and the speed, there are only two effects. The first is that ball A ends with velocity v₁ and ball B is still standing. This is what would happen if ball A missed ball B. The other result is that ball A is stopped and then ball B has a speed of v.₁. You may have seen this happen when a pool ball hits one head. The moving ball stops, and another ball moves.

This is what happens with Newton’s baby. If the collision between the balls is elastic (that is, the correct comparison) and everything is in line (to be uniform), then the only way the ball on one side hits is to stop and move the other ball. on the contrary. It is the only way to maintain kinetic energy and speed. If you want more detailed information, here is your video:

What about a continuous beat? It’s easy. Since both balls have the same mass and the same speed (because they stick together), the only answer is for both to run at 0.5v₁ after a hit. In the case of a collision (which is not flexible or immovable), both balls have a velocity between 0 and v.₁.

As a demonstration, here are three collisions. The top has a strong impact, the bottom is inelastic, and the middle is somewhere in the middle.

I think that just looks good.

Superfast Cradle Video Analysis

There are a number of factors that make the Slow Mo Guys movie collision different from the usual Newton system. Instead of five balls in the set, there is a sixth, a ball that is fired from the air. The ball is moving very fast, but it also looks a little smaller compared to other balls in the chair, which means it has a different mass.

And as you can see in the video, instead of just throwing a ball at the end of the section, four of the five balls cut off their ropes and fly away as the base falls. This will not work as a good office toy (and can put a hole in your wall).
