    Great video! I loved the "real world application" lol. It helped a bit for me to understand. If you could do more, that would be wonderful! (Just a suggestion^)

      Don't worry, I am making more. They take quite a while to make; so you'll see another video one week from today.

    How coincidental that I'm watching this exactly 3 years after it was posted! By the way, these videos are super helpful for people like me who didn't have physics offered at their high school but have to take it in college!

    Fantastic as usual, I am still using these videos to learn physics further.

      Wilson, I must say that I did have concerns when you were my student that you might not actually make it through all the videos. Therefore, I am impressed you are continuing to learn from me.
      Thanks for the compliment by the way. Also, did you enjoy seeing Geneve in this video?

      @@FlippingPhysics Yes I did. I have just started watching the most recent videos put out, it seems as though the quality of the videos continues to improve.

      I am glad you feel the quality of the videos continues to improve. Even though I have been doing this for almost 6 years, I keep learning more about how to make them.

    Lol, Loved the real life door demo.
    Keep up the amazing videos.

      Yeah, it's definitely a "real life door demo". 😇

    hey can u explain why for angle of ryan we have to use minus but for angle of G we have to use plus ? and thank youuuu

    • @FlippingPhysics

      I am sorry, however, I am not sure I understand your question. I am thinking your question has to do with the direction of the torque for Geneve and Ryan's forces. The direction of the torque determines if the torques are positive or negative. Please watch this video: www.flippingphysics.com/torque-right-hand-rule.html I think it will help.

    • @pluviophile3859

      Flipping Physics Yes now that i thought about it again thats true it has to do it with the direction and the right hand rule as well thank you very much!

    I love your vídeos, they are very creative, with the students questions and errors!! But I think you should add "k, unit vector" to the solution (!)

    • @FlippingPhysics
      @FlippingPhysics  2 роки тому

      Glad you enjoy them.
      I have a video that has torque as the cross product and therefore uses unit vectors.

    Can you explain the plus and the minus 90 for the angle

    • @babitasharma1709
      @babitasharma1709 2 місяці тому

      does it have to do something with the clockwise and counterclockwise?

  • @Plantsknowthings
    @Plantsknowthings 4 роки тому

    Why is the sine angle for G 115 degrees? Shouldn't it be 245 degrees if we are working counterclockwise from 0 degrees?

    • @carultch
      @carultch 3 роки тому

      If you account for direction by inspection, it is 115 degrees.
      If you account for direction mathematically, without first inspecting the directions you expect, it would indeed be 245 degrees, which is called the reflex angle of 115 degrees. In other words, 360 degrees minus the angle.
      You will notice that sin(245 deg) = -sin(115 deg), which means that if you didn't account for direction by inspection, you would generate a negative sign through the sine function that would account for direction for you. This is reflected by the fact that Geneve's force on the door produces a torque that is counterproductive to the torque of Ryan's force.

    Geneve, aka Generation Eve. Cute, huh, and relevant for the times. Her generation is making great strides for good women. (Just popped into my head as I started reading the problem.)
