Measuring vector quantities in nanoscale systems is challenging — often only scalar magnitudes can be experimentally obtained. Now, a multi-frequency atomic force microscopy method for ...

Ideally, I should stick with the same notation I used in Basics: Vectors and Vector Addition. But let me go over the different ways you could represent a vector.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The sum of the gravitational and electric forces is at an angle determined by the vector sum of the two forces. If the two charged masses are at rest, the Tension of the string must balance that sum ...
