Lots of stuff going over my head and that I will forget. But I love listening to a lesson and not being forced to understand it. I can just marvel at the wonders of science and appreciate all those scientists with brain capacity well over my own. Thanks for making the world better with electricity, internet, smartphones and antibiotics.
For me science definitions are always true , i always use hypothesis instead of theory in my life once i knew what scientific theory mean, and it makes sense.
OMG JINGLES I JUST WATCHED UR LASTEST VIDEO AND CAME TO THIS AND HERE U REPLY WTF WTF. OMG OMG . UR FAMOUS MAN. I SUBCRIBED TO U SINCE UR FIRST VIDEO. OMG JINGLES
if you try to read and study a bit about everything she says in parts, maybe following the same order of the series, and then watch everything again, I'm sure it will became easier. she also always say what kind of mathematical witchcraft she is using, so its easier to just go look a bit about it to make the math easier to understand.
A lot of this stuff takes repeated exposures from multiple sources. It is like anything you do, be it league of legends or math, it takes time and practice :D
I'm the same, I wish it was easier to retake my maths and science courses from school so I could actually understand these.. What grade are these videos aimed at? In the uk I only took GCSE's which we do at 16 and this is a lot more advanced than those, oh and it was nearly 20 years ago so I don't really remember much either!
Your videos are really helpful for reviewing some of the important concepts a day or two before an exam. Trust me if I would've watched this video without learning the chapter at a slower pace in school I would definitely feel lost😂😂. But thanks to your videos I've developed a lot more confidence than before. You are great teacher.THANK YOU
I learned more in 10 minutes than i did in 3 weeks of physics. This would’ve been great to have before the unit. The explanation even uses past equations so i can remember them. Thank you
Okay. Thank you so much. Today was coincidentally the day when my teacher started this chapter in school and I come home to this video while surfing YT. God bless! Really love the simple and AMAZING explanations. Can't believe a boring physics lecture in school turned into a really fun YT Physics Crash Course. 11/10 would recommend.
I just want to say I love everyone who worked on this. I'm in AP Physics right now and my teacher isn't the best at teaching (she would be better at the middle school level. She had=s the enthusiasm but lacked the ability to teach mathematical concepts). Your required to have either completed calculus already (like me) or be in the class right now (about half the class), so that means that means when it comes to some of the math, it's some kids first time seeing it. Yeah, not good. Anyway, what specifically made me leave this comment thanking you is that you actually called it an integral. Both my teacher and the text book have been dancing around the word because it hasn't been explicitly taught in class; and I have been ready to rip my hair out because I just wish they'd call it what it is. So thank you for keeping me sane.
PBS was very smart to endorse it! It is one of my fav topics on my fav educational channel. Also I invented insta travel based off of Breit-Wheeler process. Hopefully they will talk about it one day!
I'm procrastinating my physics assigment to watch Crash Course Physics. Just kidding, who would do that. I'm just a construction worker. Love the series even though I feel like a 6 year old while watching this.
I see this channel becoming the complete future of High School Education - I learned more in this video about Work than i did in a whole year back in GCSE's xD
This was a really good input. Once again, it is fantastic to explore the equations and how they describe the same concept using different terms. It is 100 times more engaging than dull mathematical exercises. Looking forward to the course on power and electricity!
Finally we start getting into real physics. But you forgot to mention the gauge invariance of gravitational potential energy i.e. you can set its zero to be wherever is most convenient.
***** When I think of physics, I think of momentum, energy, fields, and sources (mass, charge, etc). To me, forces are just a tool for practical use, not anything meaningful.
The graphics of ur videos r so... Amazing. The teachers clarify everything in less amount of time effortlessly... Also your channels contain vedios for almost everytopic.... Cheers ☺️ to one of the best channel Guys u r doing a great work thanks a lot
I wish there are explanations on how the formulas were derived, like why is it x^2 for the equation of the potential energy of a spring? Like, seeing the whole thing and how it would apply in the real world and why the formulas are such intuitively rather than just following a formula and solving.
I like this vids because they are educational which help me get ahead of my class and these are good cause when they are helping others they spread the knowledge for people to learn ☺️❤️
I may be the only one who noticed this but you were speaking slower and I'm glad for that. I really couldn't keep up on the previous episodes so thank you. #physicsnovice
Honesty, kindness and good work… work and energy and momentum. Work… fascinating how very important relativity and/or context matters. Lots of potential and kinetic energy.
I have a BS in Physics but it is well past its "use by date" (the 1980s were a long time ago) and I enjoy these videos. Great little reminders of what I worked so hard to learn.
I still remember learning that P=F*v when I was taking a lesson on aerodinamics in a Fluid Mechanics curse after the teacher stated that the power to keep a plane in flight was the Drag force times the velocity of flight, that was a really interesting thing I had never though before
Shouldn't Hookes Law for a spring be F = - k * x ( k>0) Since the direction of the restoring force is the opposite of the displacement? Otherwise you should write the equation with vectors..
Since it's not a vector equation, it really is just a statement that spring force is proportional to distance stretched or compressed. I find that, although I teach the negative sign and full vector notation, many students don't immediately grasp that a minus sign means just "the other way." This series is trying to be as clear as possible, so they left that out. In my opinion, it was the right decision for the time allowed.
There is a way to deal with gravitational potential energy that isn't relative. It comes from the fact that, using E as all energies other than potential, Ei + PEgi = Ef + PEgf. That can be rewritten as Ef = Ei + PEgi - PEgf. If we expand PEg we get Ef = Ei + mghi - mghf, and then using the distributive property, Ef = Ei + mg(hi - hf). So basically, gravitational potential energy is more about a change in height than some abstract quantity associated with a certain height.
