093 - Conservation of Linear Momentum
In this video Paul Andersen explains how linear momentum is conserved in all collisions. In completely elastic collisions the kinetic energy of the objects is also maintained. Several examples and demonstrations are included.

43 years ago, when I was about 13 and about to go into high school, My grandfather said " If you ever get a chance, take a physics course, its very interesting". Now here I am the old man on campus at community college, and I found out he was right. Its difficult, but these videos do help.....
aw this is sweet
I agree, old man. I’m only a few years your junior and I learn this stuff with a passion - just for fun. I feel like I understood the world as a child before I learned some physics. Then, the more I learn, the more I feel I have more of an adult understanding of the world in which we live. But I’m still at the stage of early college courses. My chemistry teacher said he was “blind” before he had his first organic chemistry class. Same sentiment for me except with physics.
good luck!
Greetings from another old man on campus! I haven't challenged my brain this much in *years*. But unlike those early years, I enjoy homework now!
Learned more in 7min than I did in 2 weeks. Thanks!!!
Hi George.
yah its helpful
Bro
Excellent. Helpful even for college physics. Thank you for your work.
+william maldonado Is the Vs in his kinetic formula for mass or finale velocity? please help me
+Chris P.Fries in a kinetic energy formula the 1/2 m v^2 is the the kinetic energy for an object at any one moment in time. I'm practice you would have one side of the equation a summation of all kinetic energies from your starting point equal to all the final kinetic energies. So your v could either be a final or initial velocity based on which side your v is on!
+william maldonado Thanks
I think teachers like to complicate things. I don't know why. Thank you for simplifying this!
omg so true
its true jammin,, mine like complicating things too and he made clear.
teachers are not complicating it. Maybe that was your first time learning it , that is why it’s easier for you to learn after watching the video. It is your second time already
@@JacobPolicediez it is the way it is taught, not necessarily the number of times it was taught
@@BriBorgersen
OMG so glad you made these. My college physics teacher is really smart but not good at teaching undergraduate physics. Thanks!
Currently refreshing physics for the Mcats, and these are still extremely helpful. I applaud your elevator speech sir. The ability to relate and breakdown content is amazing. I wish i had you for my high school instructor years ago.
hands down you are a Master at teaching! period!
Thanks a lot, Mr. Anderson! Taking an Aerospace course and the prof mentioned (conservation of momentum) - I don't come from a science background, so your video really helped!
the introduction is always my favorite part of his videos.
Thanks a lot. Ur video really helped. I’m an 11th science student was having hard time with this but thanks to u. Now I understood this.
Dynamic flowcharts! Great video, I like how the flowcharts are the examples, great idea
Interesting. I am not taking physics (natural resources major) but I find it fascinating. What struck me the most about this video was the terms elastic and inelastic seem to be reversed from what I would have intuitively guessed.
Thank you for your work on these videos. Your series on biology really helped me with my biology course last summer.
So helpful. It's much simpler once you think of it like this. Thank you very much!
Bozeman Science , i wish i had you as my teacher. My teachers were paedophiles, open drug users (own experience) watching porn, comedy and cheech and chong during class me being a drinker in class and self harmer, no one cared as we were ending up in the gutter of life.... I would have gotten so much further in life at a younger age. Thank you for putting these videos up.. never to old to learn.
Arjan Wilbie wtf
***** not everybody has had a happy childhood.
what kind of school did you go to? are you dutch?
I am dutch indeed. The school was a hell hole :( lower technical school... A fight i did daily
Arjan Wilbie It wasn't a school but a torture . May be you are dreaming.
Thank you for your help, once again.
Thank you so much, Mr.Anderson.
thank you soooo much!! you are a exam saviour....
I see we have some company here :)
lol maanav!!!
Best explanation ever! Thanks master
Your explanation was very helpful. Thank you.
thankyou for making this it did helped me so much
Really good video. Very educational, I can understand it, and good examples. Keep up the good work!
thank you so much its really helpful!!!!
This helped so much!
Thanks alot sir...Really helpful.
u are a great teacher . thank you
very simple and helpful!
Awesome video sir keep uploading
Thanks thanks thanks a lot for such a great explanation 😊👍
Thank you, that was really helpful 👏
You are so good! D:
Gonna show this vid to my classpartners.
what's the sad face for?
@@endiegaming3322 Ooof.. how have things changed since then. Shit. I moved from Venezuela and now I started studying engineering in a new country. Everything was ruined back there.. The sad face is not sad, it's like a desperate face requesting more recognition for this video, haha.
thank you sir!!!!😀
Thkns also this help in my 9th class of physics...thkn u sir sooooooooooo much!!!
mr anderson is A GOD
It was very useful
Super helpful.
this was so much fun
Thank you it was halpfull
ur moms halpfull
spent more than 7 hours reading the book and didn't understand anything.But then i came across this video :)
You're so good!
really....helpful...for....understand...thank..u
thank...you....for....understand...comment.........lol
great sir... thanks
you're great at teaching this topic. we dont understand our teacher lol
Superb!
Amazing
So Helpful 🤘
Thank you dad
Thank you, that was really helpful.
Sorry. At 3:21 All my gamer brain heard was 1v1 and 2v2
Thank you... we literally spent 1 day on elastic energy..... then the next day my teacher gives a pop test on elastic energy.
Thank you it is help full
rly help full, not help empty
At 6:00 you should do 150J - 50J = 100J
Damn. You're good. Thanks 😄
2:23 HOLY SHIT!!!!! LMFAOOOO THATS AWESOME!!
I think you're wrong when you say linear momentum is conserved at 0:25. There are external forces acting on the masses produced by the tension in the string (and conservation of momentum only applies for a closed system with no external forces). Hence momentum isn't generally conserved. You can also tell this is the case because the first ball is accelerating before it hits the second ball meaning that's it's magnitude of it's velocity is increasing! It is NOT conserved!
Thanks
Did anyone else notice he caught that apple when bounced from a basketball?
this was too help full
WAY too help full
why there is conservation of linear momentum in the elastic and unelastic collisions ?
I can always count on good ole' Bozeman
HE CAUGHT IT, HE CAUGHT THA APPLE
it's all good and well you say the lost kinetic energy transfers to internal energy, but what does that even mean? does the energy charge to the battery?
Energy is 'lost' by heating up the molecules in the collision. It is also lost deforming the solid, which requires energy to bend the metals and what not (in a car crash for example)
Product of the mass and the velocity, not the sum of them.
And what happens to the momentum when I hit a wall with my hand and both my hand and the wall are at rest? How is momentum conserved in this case?
And one more What happens to my momentum when I am walking and suddenly stop?
Can you answer me professor?
The earth gets + momentum, your hand gets - momentum.
momentum is product of m.and v not sum.as you said
what made the fist two collsions elastic and the third inelastic?
the matireal they are made of?
How about when is at rest
The September 11 building collapses violated The Law of Conservation of Linear Momentum.
guru
who els have a test tomorrow and didnt study?
and thanks for the vidoe
What that prime he says stands for ?
it's just used to identify it (the p1 prime+ p2 prime) as a product value. only an identification term used to make life easier while solving complicated questions
Can anyone please help me?
In his video the kinetic energy part at 4:06 and 5:01 does he mean that the V1,V2 is mass? Is the V parts in his formulas for Mass or final velocity?
Whoever answers I would like to say thanks!
kinetic energy uses both velocity AND mass. notice on the picture at 5:01 the masses and velocities are given. then look at his formula and match the object velocities to the masses. Hope this helped.
+william maldonado Thank you very much.... It really helped :')
+Chris P.Fries no,velocity
you dint explain how to calculate -_-
Hi
hi there
thank you dude for liking my comment
what if both the driver get all the internal energy! = dead ;x
DID ANYONE SEE HIM CATCHING THAT APPLE?
noice
что ты говоришь?????
я не понимаю?
Kuch samjh nahi aaya thora Hindi bhi use kiya karo
