  • wow you just made so MUCH SENSE

    you have a gift for teaching.

    that never made sense to me before.

    thank you so much

  • Funny I have a fluids exam tomorrow and am gaining confidence as I watch your videos. I cant believe I didn't see this before my first exams. Now I feel like I understand enough to actually teach someone. Captain Sal explain things so simply like you do . thanks

see all

  • Mr. Sal, you're not just a great teacher, but you're also a great magician. You helped us in showing the formula for buoyant force like magic. THANKS!!!

  • the day before yesterday:

    me: CHER! i dont understand what youre saying

    yesterday:

    --watched this really helpful video--

    today:

    me: CHER! why dont you understand its so simple!

    now i can confidently take my physics exam:P

  • @rotflmaopmpqxyz Some of it are actually arbitrary. Remember, they're just variables. And it's actually the greek rho (kind of a curvy P) that stands for density, not simply P.

  • You have saved my life soooo many times, thank you so much for what you do.

  • Thank you!

  • So P stands for pressure, and p is also units for momentum AND density? these confuse me. Also Mass and meters confuse me too

  • I have a question for you. If an object is at the very bottom of a jar of water with no room for water between the object and bottom of jar, how does the object still buoy up if there isn't water below it?

  • woah. lol

  • I've been trying to solve this question for so long. You're explanation enabled me to answer it. Thank you.

  • omg khan when im rich im guna give you so much money
