PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? 🙂 Here’s the lecture for Wednesday – Archimedes’ Principle. Great topic for investigation!
PHYSICS 2-18-14 Archimedes Principle from Tammy Skinner on Vimeo.
Ms. Skinner I don’t understand why adding mass (air) to an inner tube would allow a person to float, but they would not if that mass was not present.
J – and volume?
So filling something with air decreases density?
I think it goes back to the density formula D=m/v. You are adding both mass and velocity but since the velocity increase is more than mass increase the density ends up being lower than before. Does that make sense?
Woops that was under the wrong name
Since we don’t have school tomorrow, does that mean we only need to watch this vodcast and complete the homework problems for tonight before returning or will we have another vodcast to watch tomorrow as well? Happy snow day physics pham!
