To be clear, the energy and momentum equations are not enough to solve Newton’s cradle as some have suggested in the comments section. For anything more than two balls you need more equations to get the appropriate solution. For example you could have one ball coming in at v and after the collision have one ball going -1/3v and two balls going 2/3v and that would solve both the energy and momentum equations, but that is not what happens in the Newton’s cradle. It is obvious you need another equation besides the energy and momentum equations in order to solve the problem...you need the dispersion-free energy propagation as I describe on this video.

One more thing to point out, notice that when the balls stopped bouncing but all the balls swing together in unison? All of the initial momentum eventually spread evenly over the 5 balls before coming to a standstill. A similar result can be achieved by using two mass-spring oscillators connected via a third spring

As some have stated, the force of gravity pulling down constantly seems like it would play a big role in slowing the balls down. However, this is not the case. When the ball is going up, gravity slows it down until its apex, but then gravity speeds it up at the SAME RATE on its way back down. Toss a ball in the air and it returns at the SAME speed due to this principle.
@misterexclusive82825 жыл бұрын

@misterexclusive82825 жыл бұрын
@True WingChun gravity is a downward force, so if you have something blocking an objects trajectory downward, then yes, it will slow down. But if there isnt an opposing force, the object will continue to gain speed until it reaches terminal velocity. The only time gravity slows an object is when an object has been moving faster than its terminal velocity in space, and when it enters earths atmosphere, it decelerates to its terminal velocity. However, this is not due to gravity, but to opposing forces *of* gravity.
@bennemann5 жыл бұрын
Actually, because of a phenomenon called the terminal velocity of free fall due to air friction, if you shoot a projectile upwards very fast, when it comes back and hits the ground, it will NOT have the same speed as when it left the gun muzzle, because air resistance will impose a hard limit on the maximum speed attained by the bullet. Your assertion is only true for objects going upwards at **low** speeds.

You are right about the shockwave but the energy loss isn't just from the string friction but from the fact the cradle doesn't have perfect geometry and the shockwave isn't directed precisely through each ball's center of mass. So each shockwave loses a portion that depends on the angle that the shockwave travels and the horizontal field where the centers of masses rest.

The heat then escapes from the balls as infrared light, into the air once the vacuum is released, even a tiny bit into the wires also: it's not a perfect vacuum. In fact, neither is space! Very low frequency sound waves can travel with very few particles present. The metal balls knocking against each other probably don't produce that kinda sound though, it's more like astronomical events and stuff that can make such sounds

Same here. I've never heard that friction or drag is what causes these to stop, and if you're completely ignorant about physics, you wouldn't even consider that.

Motion loss through frictional heat is one aspect yes, but these masses are also heavily influenced by gravity (force) which slows the motion down as they want to be closer to the earth (straight down).. in simple terms.

If you're talking about a perpetual motion device then we already know it's not possible. Every system has a small amount of energy loss due to things like friction and heat generation which eventually causes the system to slow to a stop. And even if you did succeed it would be useless because any method used to generate electricity would be an energy drain on the system causing it to slow to an eventual stop.

Actually the difference is not negligible almost 3 sec from 11 to 14 seconds wich is a gain of more than 30%
@gronblom5 жыл бұрын
That may be due do not having any loss due to sound, since there is no air for the sound to move in, thus no energy is lost by sound energy. Air friction IS NEGLIGIBLE with the small size, slow speed, and aerodynamic shape of the balls.

3 seconds is negligible compared to the infinite time it would keep going if there was no energy loss in the form of sound and heat.

@MrBrew43215 жыл бұрын
I was thinking about it before viewing the result and predicted three or four hundred percent gain. 30% was disappointment :/ … I figured the heating of the string would be negligible and the air resistance would be super low, but less negligible - hence not and indefinite swinging. In retrospect I can see how the vibrations could carry through the strings -> supporting bars -> to the base and then out the chamber.

@m818955 жыл бұрын
Im far from an expert in the area, so take everything with a grain of salt. From a quick search ive found that UV rays have been proven to not help whiten the teeth and is more likely too cause damage to teeth, lips and gums including increased change of cancer in those areas. so stay away from UV. There are no scientific studies showing evidence that charcoal help whiten the teeth either, although it has neither been proven to not work. if you want to whiten your teeth i suggest looking into other things which are supported by scientific studies.

@BharathinfinityHegde5 жыл бұрын
Well a more simple way to explain the reason why only 1 ball swings instead of say 2 with half the velocity or three with a third of the velocity is because then the kinetic energy wouldn't be conserved. The collision of the balls is nearly elastic as you pointed out, the kinetic energy must be conserved. If the incoming ball (mass m) collided with a velocity of v then it would have a kinetic energy of (½ . m . v²) If suppose there were 2 outgoing balls with half the velocity the total kinetic energy of theirs would be ½ .m. ( v²/4 ) + ½ .m. ( v²/4 ) = ½ .m. ( v²/2) This would mean the kinetic energy is not conserved. The shockwave reasoning is not satisfactory as telling that a system "knows" what to do is a non scientific explanation. Besides you talked nothing about what the shockwave even is.
