Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This is the greatest educational resource in the history of mankind and I feel interminably lucky that we get to use it for free.
God bless Khan Academy and God bless it's inhumanly awesome founding members.
Sorry, I have an exam tomorrow
This is my life. Night before an exam, Khan Academy saves the day
You all prolly dont care but does someone know a trick to get back into an instagram account..?
I was dumb lost my password. I appreciate any tricks you can offer me.
"big fat juicy apple"
Hi dear khan academy. You're really doing a great job for students all over the world who can't pay bucks for online/offline tutoring. I'm gonna donate $20 every month to Khan Academy. Love it
you saved the friggin day pal!!!! I'm a musician who very stupidly got himself mixed up with physics when writing an essay about drums. Now I'm feeling like Newton wasn't chatting jibber-jabber the whole time. Shit just makes sense. Damn you save my bacon G!!! Absolute legend.
yeah, you're a real newton.
You have no idea how helpful this is! A thousand times thank you!
uhm! whoth used an orange just because he/she wanted a "big fat juicy apple"? hahahaha but still THANK YOU Khan!!!
should the velocity were solving for be velocity final, not velocity initial though?
gravitys external impulse is negligible.......... he didnt adress wind , if someone did this in a tornado it would be different than if someone did this in a still greenhouse
no, u get a smashed orange and a smashed apple
why would you do this
Sorry, but for me it looks wrong. I doesn't make sense... The momentum of the system can't be 0.4*5+0.7 = 2.7 , no, no, no. If the system is closed then you can't say what fruit is resting and what is moving, it is the same, right? If so, then we can calculate it as 0.7*5+0.4=3.9 Obviously 2.7 is not equal to 3.9. I think the correct way to calculate the momentum may be like this 0.4*5 + 0.7*5 = 5.5 Actually I am very rusty on the subject, that is why I am watching the video, but your way to calculate it doesn't make sense for me.
The change in linear momentum of the orange must be equal to that of the apple. But in this case it isn't equal. So this is wrong.
its not wrong lol
Thats what I was thinking how is the momentum of the apple Higher than that of the orange, howi is it possible that the orange hit the apple and made it gain momentum lol?
