The Physics Philes, lesson 84: My Damp Collection

Last week we complicated the idealized models of pendulums by looking at pendulums as an extended body. Today we’ll further complicate things by adding some other, real-world forces. So far, the oscillating systems we’ve analyzed have been frictionless. We’ve been dealing with only conservative forces and the total amount of …

The Physics Philes, lesson 9: Minor Successes!

In which practice problems are done, help is acquired, and more practice problems are done. If you will remember, last week I tried to explain friction forces. Except I didn’t include any math, because I didn’t really know what I was doing. This week, you’re in luck! I worked really …

The Physics Philes, lesson 8: The Electric Slide

In which books are moved, boxes are not moved, and math is avoided. I’ve spent the last few weeks trying my best to explain Newton’s three laws of motion. It’s been a pretty wild ride, but now it’s time to move on. This week we’ll look at some forces that …
