    Joanna. I can’t reply directly because for some reason you Tube does not
    allow me to do so on your comment. But the answer is no. This is because
    the pressure is transmitted through the fluid not through the solid

    You are very good, you make root concepts simple.

    Very nice job, I appreciate for your video. I am math major and just began
    to study physics with help of your video.
    I have one question; the mass of the floating material is the same as the
    mass of water whose volume is the same as the volume of the material
    beneath water.
    I wonder, in case of heavy material which is drowning in water, whether the
    material keeps drowning or stops drowning at a certain depth of water if
    the water is deep enough like a deep ocean.
    If the material stops drowing at a certain point and maintains equilibrium
    inthe water, what is the relationship between the density ofthe material
    and the depth of it inside water.
    I hope I made my point clear. Thank you anyway. My best wishes.

    Trying to figure out the force a cylinder must generate when it is
    subjected to 17,000 N at a 20 degree angle, every time I enter the equation
    in my calculator it gives me the wrong answer. What am I doing wrong? Why
    am I so dumb? Lol

    You really are the best teacher mate !
    Thanks for all the videos !!

  • Naxween KickAce says:

    this helped a lot 🙂 

  • Joanna Lada says:

    Thank you for another great video! Your explanations are always so clear. I
    just have a quick question: at 22:05, you write P(2)=P(A) +h(2)pg. Do you
    not have to take the heights of water and of the cylinder separately? I.e.
    should it not be
    P(2)=P(1) + [h(2)-h(1)]p(cylinder)g? Thanks for any replies :)

    you’re the best tutor,,I guess,,,:”

    You have an awesome pronunciation of words (Y)

    Everytime I see a woman with a Great body I remember what Archimides said
    …. Give me a place to stand and a Pecker long enough and I can Fuck the
    world !! ha ha ha ha ha ha 

  • Liiza Stuart says:

    You talk real fast,everything is right I guess but I’m not going to pass my
    test with you talking too fast so please slow it down.

  • Deuce1042 says:

    Never heard of it referred to as up thrust. Typically I hear it as the
    buoyant force. Interesting

  • bob marley says:

    24:07 onwards is all you need for edexcel physics 2013/14

  • Tamy.Shlomo Bachar says:

    Very well explained! Very good videos!

  • Pavly sz says:

    im in egypt we learn it at 16 !! 🙂

  • DrPhysicsA says:

    Ah. I have a steady supply of pens.

  • DrPhysicsA says:

    Thanks for your comments. I suppose it depends what depth you go into the
    subject but the material covered in this video would in the UK normally be
    for those aged 17-18.

  • Secular Talk says:

    lol thats like the most important thing

  • ashik panigrahi says:

    how can u be sooo good man….!!

  • DrPhysicsA says:

    A less dense fluid will float on a more dense fluid. That’s why oil floats
    on water. So if you want to use the experiment in the video to measure the
    density of a fluid which is more dense than water then you have to use
    another fluid instead of water. You need to know the density of that fluid
    and it has to be more dense than the fluid whose density you are trying to
    measure. Density is mass per unit volume.

  • Andrew Teoh says:

    Thanks alot sir you’ve cleared my doubts.

  • GHADA abdul aziz says:

    That certainly made things quite simpler .. your explanation is very
    well-organized and It really helped me ! Thankyou ! 😀

  • MrKrissh999 says:

    THANKS SO MUCH FOR THIS VIDEO! My teacher didn’t tell us how
    upthrust=weight of fluid displaced!!!!

  • ashley simson says:

    me too in guyana

  • DrPhysicsA says:

    Depends what level you want. My current series on Quantum Mechanics
    concepts covers superposition of states extensively.
