@@Sargent_JoWell it should arrive almost exactly where it started from, meaning that yes, a slight movement could harm you. The trick is to create a bit of drag when you let go of it, such that there’s a good extra 4cm when the ball returns. You can tip it the other way, you can hold it a little farther away, or, when it’s slipping out of your fingers, let it slide out.
@@ilikeanimals5015why don’t you look up all of the perpetual energy machines and how they’re all hoaxes? They don’t work. There’s always a hidden battery/motor.
This was done many many years ago by a dutch scientist called walter lewin he is incredible and i highly reccomend you watch the 1 hour lecture. Its amazing the way he teaches.
I remember seeing a viral video a few months back about a science teacher demonstrating this exact experiment, but he was blindfolded. One of the psychopaths he was teaching pushed on the ball on it's return path, and it barely missed the teacher because the trajectory was altered to be /just/ off course from the bowling ball smashing into his head.
Why didn't I flinch? The laws of science differ fundamentally from.... *gets annihilated* 😂 @@Samandjam555 Here before this comment blows up, BTW I was looking for this same comment.😅
Just don't push it and gently let it go and you'll be fine. It's impossible to get hit unless you give it a force like pushing or you moved towards the ball.
I got goosebumps from just watching it swing up to his face just so close to hitting it. Knowing me, I would've just got hit only cause of moving with nervousness. 😂
@@alexanderadams9058 Its not a Cello, Cellos cant play that loud at that pitch. Its a weak synth mixed with violin mixed with trumpet so the original commenter is technically right
@user-pm8jq1nb1e he didn't do it first, there are old black and white videos of Richard Feynman doing the same experiment in class. I'm guessing this goes back even before Feynman.
I just discovered this channel!! The Museum of Science is really close to where I live and I used to love going there when I was younger! This brings back so many memories ❤
@@kadafinancial3596 it doesnt matter which way you push it. if you push forwards it now starts with gravitational potential energy + kinetic energy, so it can go higher up at the max height where all the kinetic energy is now part of the max grav potential energy.
To quote mythbusters: "the only difference between science and screwing around is writing it down" Science is just testing what we know/think we know about the world, and trying to understand why things work the way they do, so we can make things happen the way we want them to
@@samuelmellars7855science is just x but that x is actually very hard. An experiment is rarily so simple in nature anymore so we have to use complex math and logic to sort things out. Its a mindfuck until we can make the claim that we know something and even then we are not sure. Even our most scientific beliefs are innocent until proven guilty. Unfortunately that is how things are but we’re doing pretty good so far.
The potential energy is when the energy is being held, like a battery. The kinetic energy is when the energy is in movement, like a crank powered toy. Well done!
