It’s just the conservation of momentum from the initial upward movement. If you have some friction or impedance, that can negate it. Your 2D floor test proves that. Fancy science dudes don’t know what they are talking about. They got BOOMed.
Yeah it's inertia. It's like a vehicle suddenly accelerates and you'll be slightly left behind. FG=mass*9.8m/s2 and it gradually becomes heavier on the falling side thus the greater the inertia and the effect.
If a chain truly falls faster than other objects (assuming this is meant as "in a vacuum") because the lower links exert additional force on the upper part (as I believe the study concluded), then that difference between the "normal acceleration of gravity" and the rest state probably manifests in the energy of the loop being thrown upwards. How? Erm ... my money is on Eldritch magic.
I think both options are at play somewhat however i do think medhis answer is definitely the most prominent and that the effect of the leverage is very minmimal.
Theres no reason to count just how much you save for 100km... Counting how much owning car costs per km is the only way. And i can tell If you count very very expensive car +all other costs + depreciation driving newer EV is just dumb.🤭 My old Audi A2 1.2tdi has averaged consuption of under 4 liters/100km(60mpg)and in freeway speeds it goes even further, over 75mpg(3liters /100km) And car is basicly worth maybe 4K€ .that + insurance and upkeep costs are like 14€ sents(17$ cents US, 20$ cents CAN) per km annyally.that includes fuel, insurance,services with averaged km per year being ~10.000kms
Came here from the Mould video. Two minutes in. So far it’s been…abrasive. Edit: okay, it got better. Just a bit more frantic than I’m used to. But maybe that style captures more eyeballs than other edu content. Can’t fault that.
It depends on the thermal conductivity of the material to put it simply some like silver and gold r more conductive of heat n electricity and flow of electrols die voltage will be higher in those materials.... Look up thermal conductivity to Resolve that
Why on earth this video is age restricted and why half the comment section have misunderstood that it was just high current not high voltage , everybody can survive that and noone would call them immortal
Thanks for the video. Yeah. It does look like it's essentially a centrifugal force / conservation of angular momentum that keeps the chain follow an arc.
i just commented on steve mould's channel saying its a whip, you can do this with almost anything, like rope cable... well at least when its on the ground.
the music made it more difficult to understand what you were saying. and your accent already made it difficult to understand what you were saying without music. i have auditory processing impairment and tinnitus as well.
I mean, _of course_ he doesn't have any other crew. Who would want to work with this unchained lightning bolt? His channel's doing well, but I doubt he could cover insurance for anyone else, much less salary.
EB, the problem with the floor examples, is you are creating a fulcrum, where as in all of the AIR examples, there technically is NO fulcrum. So anything on the floor could have some LEVER effect explained. IMO, the bath bead chain is probably working so well flowing up and out of a glass because of weight, speed, and oddly, aerodynamics. Your larger ball, further spaced air example, only slightly worked because you had an aggressive start. Bath chain is more weight consistent, more aerodynamic, more fluid, and still weighs less. Probably the most overlooked and unrealized part of the FLOOR fulcrum effect is that what ever that furthest fulcrum point is, that section will TURN before it actually moves position, and when it turns, it further feeds the entire motion.
I think the Cambridge scientists over complicated their analysis (not uncommon for physicists). I’m with you, the change in momentum with respect to time equals the force. There may be more nuance behind the system though (each concept could contribute, and maybe another concepts contributes), but I think the largest contributor is “conservation” of momentum (technically not conserved due to the gravitational force but I think the initial pull up and then quickly changing to downward is a much larger acceleration, and therefore larger force, than the gravitational force, then the gravitational force drives the system to completion).
