Electrons in Orbit (Electrical Properties of Materials #4)
What is so special about silicon? Why are some materials more conductive to electricity than others? Where does static electricity come from? This 14-video lecture series introduces electronics from a materials perspective, and is based on a course which all freshman engineering students take at the National University of Singapore.
In this video:
00:11 Comparison of the Coulomb force to Newtonian gravity
01:40 Stability of orbits and the inverse square law
04:07 Orbits of Earth and Venus around sun
04:58 Gravity as warped space
09:32 If our solar system had two suns instead of one
11:17 If our solar system had sixteen suns instead of one
13:06 Bound orbits versus chaotic orbits
Nearly 70 additional practice problems are available in the MOOC version of this course, along with supplemental videos:
