Elastic and Inelastic Collisions

  • When you take a shot on a pool table or tackle someone in a football game, you're participating in a collision. But the two events we just mentioned are totally different kinds of collisions! But what are elastic collisions, and what are inelastic collisions? We have to learn the varieties and what they mean for momentum and energy.

    The way you make physics easy and interesting is rare, most youtubers and professors make me want to drop the book on my head, and on top of that I'm studying from Physics by Serway as my main source so it's not much help. Thank you once again! You're the BEST!

      There are a multitude of possible reasons. Many have simply lost sight of the basics and may or may not care enough to "dumb" their physics knowledge down in order to be able to properly teach it.

    Likely because it is 6am and I'm not running anywhere near full speed, but I was trying to get my mind around why we cannot use U-238 directly in weapons or more importantly in RTGs. The short answer was "because U-238 is famous for its inelasticity". My brain went offline and smoke came out of my left ear along with some sparks. Thanks to your down to earth explanation, I grasp it entirely and immediately. Thank you, brother. Sometimes you just need a nice (figuratively speaking) cup of mental coffee. Cheers.

      ​@@plankalkulcompiler9468 considering how much we pay to go to college or uni, one would think they put a lots of effort, like Prof. Dave does here, into helping average students understand a rather not complicated subject.

      you are under peer pressure as you don't feel like asking questions as you think your peers will look at you in the wrong way. at home you are comfortable... change your attitude and you will learn and don't get distracted in class

    • @drened8502
      @drened8502 2 ปีที่แล้ว

      I think its because lots of professors and teachers love explaining how formulas are derived, which confuses and demotivates many students. I know everytime I see an integral in an equation I want to blow my brains out

  • @ninaperry2873

  • @waffleface5940
    @waffleface5940 3 หลายเดือนก่อน +2

    I really want to thank you. I knew I liked physics but the class i have been taking is really focused on deriving the equation over explaining what anything is. This has definitely resparked my joy for the subject.

  • @lepoggere613
    @lepoggere613 3 ปีที่แล้ว +1

    The comprehensions that you put at the end of every lecture is the best thing. It allows us to solve a real life and exam problem with the stuff we have learnt in the lecture. And since it's just after the lecture, we can test our understanding of the lecture freshly just after watching
