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.

I'm taking an online physics class and was just not enjoying how confused I always was. Thanks Prof. Dave!

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!

Teacher : can’t teach online
Proffesor Dave: where did that bring you? Back to me

[ManoCraftas]

Why can't every physics teacher or a professor explain it that simple

[expiredoats]

this video just taught me what my physics teacher couldn't in the course of a few weeks. you just saved me from so much stress and potentially saved my grade, thank you for being so concise with your information and keep doing what you do :, )

[MrFarber]

Got my exam in classical physics this week, been reviewing your playlist, the comprehension I get from you is priceless! thanks man

[ninaperry]

Your videos for physics and biology are the best! I've tried watching so many but your simplistic explainatation and practice at the end/summary is great!

[nightbt]

THIS IS EASIER THAN I THOUGHT.. WHY WHEN I DO LEARN IN MY CLASS.. I DO ALWAYS BEING STUPID BUT AT HERE I FEEL IM ACTUALLY USEFUL LMAO

[dulminperera]

Whoaa! These are what you call 'real academic videos'. Great job!

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.

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

Proffesor Dave you explained this topic in just 5 minutes which I was trying to understand for an 2 hours really Thank you so much !!

[waffleface]

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.

[inferior]

I was having a really hard time doing physics and after I watched this I was so relieved cause now understand it so much BETTER

[pikojutjut]

My teacher takes an hour and a half but you explained it very well detailed in just 5 minutes.
My teacher should learn how to teach like you.

[olusolaadeniyi]

Thank you Professor Dave,
I use your project as introduction instructional Resource Material for my Physics Student here in LAGOS, Nigeria.
God bless you tremendously. Amen.

[isabel]

thank you for explaining this! we looked at the formulae and did questions in class but didn’t even cover what it actually means for a collision to be elastic or inelastic 🤦🏻‍♀️

[colonelh.s.l.]

Extremely valuable explanation! Thank you for making the excruciating physics into something simpler!

[gwynmarie]

Our Physics teacher always dumps the formulas and problems without explaining them right. I always feel frustrated cause I don't know what formulas to use. But with your videos, I was actually able to solve a problem on my own! And that's a big deal to me.^^ Thanks so much Prof. Dave!!!^-^

[jabez]

Thank you Sir! An hour and a half of teaching summed up in just 5 minutes.
