When you hear the word "work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in physics and today, Shini is going to walk us through it. Also, energy and power!

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.

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!

But thanks to your videos I've developed a lot more confidence than before. You are great teacher.THANK YOU

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.

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.

I'm really looking forward to when they do voltage, resistance, charge, current, etc. !
