In this video I talk about how a Newton's cradle works and a piece of the explanation that is usually left out. Then I put the Newton's Cradle in the vacuum chamber to test if there is any difference between the cradle in air and a vacuum.

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

@gronblom 5 лет назад

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.

@misterexclusive8282 5 лет назад

If gravity slowing the balls down is the consensual belief of the comment section, then I fear for humanity.

@misterexclusive8282 5 лет назад

@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.

@bennemann 5 лет назад

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.

They are just converted into another form of energy, for instance, thermal energy.

@placeandthink8728 2 года назад

yeah, the balls probably convert a little motion into heat when they compress/expand elastically. 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

My predictions before finishing the video: friction heat will slowly drag away energy

@hmw6237 4 года назад

Fascinating. My only real additional thought is to wonder if using the magnet imparted some residual magnetism to the ball that caused it to "stick" a little to the first ball that it hit which would slow things down.

Unless you use a magnetic diode, the magnetic field of the magnet can only be extended. It can't be transferred.

Can you explain the science behind charcoal on teeth or the gel with UV rays on teeth to make them white

@masonfio33 5 лет назад

Do that action lab!!!

@m81895 5 лет назад

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.

@@m81895 Charcoal is used in toothpaste and such as it is good at removing stains. There is value in it's use in those substances.

@m81895 5 лет назад

@@benjaminswartley1803 yes i saw that when i read about it and people claiming it to remove stains. im just saying there isnt any scientific studies which shows evidence that charcoal actually help remove stains. And i dont take what people say for truth, after all there are still dentists providing UV treatments despite it having been proven to not help whiten teeth.

@boomjonggol5757 5 лет назад

I watched in another Action Lab video that charcoal is actually a very fine abrasive. So.. other than the bacteria, you're scraping teeth off too, generally speaking.

@Sciguy95 4 года назад

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.

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.
