Abstract:
In this lab electromotive forces in a solenoid were observed and compared with their time
dependences predicted by Faradays Law. This was done using equi

In the first part of this course we discussed what is
known as kinematics, which is essentially the
description of motion.

The Generic Equations of Motion
Physics Lazybones
We found in the previous lecture that predicting
motion consists of calculating integrals. We are
too lazy for that.
