    In the calculus, Why did you get pounds (lb) when you are expecting units of Force, like for example Newtons (N)?

    • @CivicMikey
      @CivicMikey 2 місяці тому

      Because the inputs were in lbs and inches

    So an old English long bow user (pulling a 200lbs bow) would be able to separate it then?

    At 0:45 - "Just imagine the air being sucked out of there" - well, yes - if you were looking at any other video - but in this video, rather imagine the air being pushed out of there by the remaining pressure of air (low though it may be) being higher than the pressure in the vacuum pump. That's why you can never get a perfect vacuum - because it always takes a bit of pressure to push the remaining air out.
    OK - call me a nerd!

    01:54 - aren't you actually letting air back into the interior as the vacuum had already removed the air from the inside?

    I'm here in the year 2021, I can't even make such strong vacuum and how did they make such strong vacuum back in 1650 without special rubber seals or gaskets? legend says that 8 horses on both sides can't even pull that vacuum out... Non of this makes any sense without introducing the facts of its purpose and origins...

    Why don't the hemispheres crush due to air pressure when there is no air inside? Pls help.

  • @abrarshahriar4039

    Sir, sometimes we find it's difficult to open a container lid..Is it because of the same phenomenon??That it creates a low pressure region(If it is then how is it created??).Probably it's not vacuum inside!!Right???Sir, I need help?? Help this miserable??Lol

    • @physicsdemos
      @physicsdemos  5 років тому +7

      In my experience, opening container lids is more a matter of overcoming the friction between the lid and the container than any pressure difference. I doubt there's much of a pressure difference between the inside and outside of typical containers, but I don't know for sure.

    • @vrgamers9312
      @vrgamers9312 3 роки тому +1

      But if we heat and cool the container only then

    So theoretically if we pumped the air out of a human, they would become very powerful.
