The Physics Philes, lesson 11: You Say You Want a Revolution

In which circles are drawn, hammers are thrown, and pi is served. Until this point, the only motion we’ve been dealing with has been motion in a straight line. But guess what! Objects don’t always move in a straight line. Sometimes they move in a circle. But don’t worry. There …

The Physics Philes, lesson 10: Resistance is Fluid

In which fluid is defined, terminal speed is reached, and I still can’t do calculus. The last couple of weeks I’ve discussed friction forces and how they are applied through a few example problems. However, I only discussed three friction forces: kinetic, static, and rolling. There is one more aspect …

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 …
