Physics class
we're used to seeing things from a particular point of view that is from a particular frame of reference and things look different to us under different circumstances at the moment you look to...

These diagrams are kind of giving me a hint as to how we might incorporate energy lost to heat into our calculations involving conservation of energy. So actually what I want to know is which of these...

Now, we can solve for the acceleration of block 1. Well, the acceleration is going to be caused by how much bigger this force is in this force or FT - m₁g and that's going to equal m₁ a₁....

And I said this was the best answer, but don't worry if you put something different. Let's see what Dr. Fara has to say. [Patricia Fara] There is one thing that everybody knows about...

The answer is this one, and now, I'm not going to go through all of these other four cases. I'll leave that to you to show that in each of these other four cases, the total work done...

Well, let's think acceleration is zero which means force is up, must be balanced by forces down. What are the forces up, well these two combined. Our force down is just mg and we're...

For the first doctor, we have three data points. Data point one, well, it's observed value was 2.00 and the mean was 2.00. It’s actually a distance of 0 from the mean. The absolute deviation...

And so I sort of did process of elimination on this one. Let's see. If it starts up here, that means the velocity is 0, right? Well it can't be the blue graph because the blue graph...

Answering the question of where am I when you're at sea is not so easy, but luckily you'll only need to know two pieces of information. The first is latitude and may be you remember...

This negative makes me think we may have made a mistake, so let's look at our variables. Well, we said the initial velocity was 20 meters per second. Yeah, that was absolutely true. We threw...
