Physics class

A great place to try out our skills with this new found tool of energy is on a roller coaster. If you ever look at a physics book, I promised you on the chapter on conservation of energy you will see...

All right. Are you with me? It's time to push forward into uncharted territory. We're going to go out of the first quadrant. When we look at our axis like this. Remember we called this...

Let's go back to the experiment. We know he used an inclined plane to roll balls for the purpose of slowing down the motion. We know he used a water clock to measure time. This water clock...

Hi. My name is Paige Lee. I’m a college advisor in the College of Letters & Science. Welcome to Cal. I’m going to talk a little about having a balanced program. Having a balanced program is...

These equations are definitions of velocity and acceleration, but we can also use them to make some calculations. For example, let’s suppose I drop a ball 5 meters and it takes 1 second for this ball...

I am studying cold matter in my PhD So I am making ice cream here but cold matter is a lot, lot colder than that We're cooling atoms and molecules down to mini-Kelvins and micro-Kelvins The...

If your brain is getting a little fried, stick with me for a little bit longer. We've got one more thing to talk about with motionlessness, which is actually surprisingly fascinating. I want...

Now, let's go back to our mass bouncing up and down in the spring. You noticed I've changed it from being a horizontally sliding mass to a vertical one. The thing I like about this...

Well, we have a right triangle--we know something about the side opposite α-- that's the length of the shadow--and the side adjacent to α--that's the length of the bar. Opposite and...

Let's look at a triple pulley. We'll first see have a triple pulley work. We would wrap around this top pulley. Go down around the bottom, wrap once more around the top and then...
