... Vectors: We will for the moment deal with 1D and 2D cases. A scalar is a quantity that has a value, but no direction. A scalar can be positive or negative. Scalar arithmetic is the usual stuff you learned through grade school: addition, subtraction, multiplication, division, and raising to a power. ...

... So far we have formulated classical mechanics in inertial frames of reference, i.e., those vector bases in which Newton’s second law holds (we have also allowed general coordinates, in which the Euler-Lagrange equations hold). However, it is sometimes useful to use non-inertial frames, and particula ...
