Hydrostatic Pressure Force "must" be perpendicular Hi, I'm taking AP Physics B and we started learning about fluids and pressure. My teacher told me that the pressure of a fluid acting in a a container only applies a perpendicular force to the sides, which doesn't make sense. If you 'zoomed...

I'm learning about polarization and something has me a little confused. I feel like I understand polarization: blocking out all the light except for those waves in a particular direction: horizontal, vertical, e.g. But if a "single" light wave is made of a propagating electric and magnetic...

As a future physics teacher I've been looking online for a good Newton's cradle. Unfortunately all the ones I come across are cheap and my prior experiences with them have obviously been of rather poor quality. I was wondering if anyone knows of any sources for high quality Newton Cradles; I'm...
