This question started out as a thought experiment on a flight home from Japan a couple years ago. I've toyed with it since, but I don't know the best approach. I'm hoping someone can guide me in the right direction. I don't want the answer straight out, I'm mainly looking for a good way to...

Thanks so much for sharing Wellesley. Useful information!

Good point. This is really a question that needs to be asked by any student taking classes that they plan to transfer to another school. The courses I've listed are all regionally accredited, so yes, they "should" transfer, but you need to check with the school you plan to transfer to in order...

First, in reply to your original comments: "My question is, how is an online course any better than just buying the textbook?" If you're just looking for knowledge, there's little benefit other than access to a professor who should be able to answer any questions that come up. If you're...

This is an old thread, but I'm pretty sure that there are others out these looking for this as well. In fact, a friend of a coworker was looking for online physics and chemistry classes recently, and here's part of my reply. Hope someone out there finds this helpful! If you just need to take...

I think the question really is "Can an electrical signal be truly digital?". The world is pretty much analog by its nature, but digital signals are really only 'digital' because we've defined a certain signal level as 'on', and a different level as 'off'. It's only be convention. Something made...

If it were easy, everyone would get to do it. And where's the joy in that? Seriously, as a Physics 2 student myself, I feel your pain. I've found it helps to buy or borrow from the library book along the lines of what you're learning in class. Sometimes reading the same thing worded a bit...

Can you post a picture of the graph? If you're comparing two signals, you can compare their peaks (or where they cross the x-axis), and use the difference to compute the angle. I'm including a picture. The purple distances are both equivalent, and demonstrate the phase difference between two...

Assuming air resistance is negligible, the horizontal component of initial velocity and of final velocity are equal, but they are not equal to zero (unless the object has been dropped straight downward along the y-axis, in which case there is no horizontal component). So when the object hits the...

Consider an x-y plane. If you move a particle directly to the right, it doesn't influence that particle's motion upward or downward (y) at all. Similarly, if you move the particle directly upward, it doesn't influence it in the left or right directions (x). But either of these will influence the...

I passed my math in High School, but with consistent D's, if you can really call that a passing grade :) I think the teachers felt pity for me. I wish I'd paid attention back then, because only now (8 years after graduating High School) am I really starting to have a solid mathematical...

alphysicist's suggestion makes sense. If we consider the time interval to be from t=0 to the point in the word problem where Joan is ahead of Mike (and we stop our time interval there. We're not considering anything further. Our analysis is just from the time they start, until the time described...

Well, I must admit I was a VERY poor student through High School. I was bored, and didn't consider that the things we were studying at the time would be a foundation for the more interesting things to come. When I discovered the joy of physics, for the first time in my life I WANTED to learn...

ebaywannabe: Thanks for the info. It's not too useful for my specific inquiry, but it's interesting info none the less. I was previously aware of the MIT work, but I didn't realize Berkeley had done anything like that. Thanks for sharing! Once I actually find a good online calc-based physics...

Just an additional note, the algebra-based course I took came with two lab kits. They weren't cheap, but they were good. Each lab required exactly what you mentioned, mechanically handling hardware items, arranging them, preparing what you will arrange, test measure and observe, with the...
