Elastic and Inelastic Collisions

094 - Elastic and Inelastic Collisions

In this video Paul Andersen compares and contrasts elastic and inelastic collisions. In all collisions the linear momentum will be conserved. In an elastic collision the kinetic energy of the objects will also be maintained. Several examples and demonstrations are included.

So, to answer your question "was this helpful" I will say, you made more sense in 6 minutes than an hour of my college physics 211 class at Portland State. My professor tries to make himself look smart or something because he talks about deriving the velocity by taking the integral of some nonsense and often times give overly complicated example equations but doesn't give us time enough to write them down then doesn't show how he gets to the final equation and after an hour and a half I have no idea what he rambled on about and no clue what was the important take away equation.

So I turn to YouTube. I have found so many awesome professors here, you are one of them I am now adding to my list. Thank you so much for this clear and easy to understand explanation. I not only have a better understanding of the difference between elastic and inelastic but I also have actual equations that I can use to answer questions now.

Thank you for posting this and I hope you have other stuff I can use. I see one over in my right panel that is a playlist of your videos and the thumbnail looks like one of the things I need next. So glad I found your videos.

i have my weekly test tomorrow and this video has saved me.

Thank you for your videos. My physics teacher confuses me so much but I understand everything now :D

[Isaacnjw]

thank you so much! you've made my notes simpler to understand!

[nathancoleman]

saved my life the night before a physics exam :)))

[kuzain]

Easy to understand I learned a lot from watching your videos, really helps understanding the basics. I wish you were my professor

For those didn't got the total momentum conservation. Suppose there is a guy walking and you go running straight to him after the collision your velocity and that guy's velocity will get distributed among you both which will be different from the velocity before collision. Hope this helped :)

صراحة كثيير حلوة طريقة شرحك واضحة و شاملة من كل الجهات
really i loved way your explanation clear and comprehensive from all sides

[parthwighe]

today is my exam and this was the only thing I couldn't understand thanks to you. now I understoo this whole topic

[bharatvadisherla]

best physics teacher and easy to understand

[mohinichaudhari]

So helpful...just help before my Exams

[hamzabaig]

TY SO MUCH!! THIS IS WHAT I WAS LOOKING FOR.

[dannggg]

i dont understand anything in my physics class. watch your video once. i understand. thank you so much

[soapywaters]

Thank you so much for helping me understand these things! I hope you're all right during this pandemic. Take care and may God bless you 💖

[Redfox]

You're videos are very helpful! Thanks!

VERY HELPFUL I CANT WAIT TO SHARE IT IN MY CLASS THANKYOU <3

[ashishmahadasyam]

Great teaching is amazing....thank u very much...sir.

This is a brief lecture so thank you for your precise video

Hi! In class, we've seen that linear momentum is only conserved in isolated systems that is to say systems on which the forces that are exerted cancel each other. But here for falling objects you apply the same rule even though they are in free fall and should therefore not be considered as isolated. plus, when you first dropped the ball on the floor and it didn't rebound the linear momentum of the system became zero, what happened? 
When can we say that linear momentum is conserved?
And why did the two carts stick to one another in the inelastic collision example?

keep making videos like this one love it
