01/02 | General
principles: basic quantities, ideal models (e.g., particle),
Newton's laws of motion & gravitational attraction, SI units &
prefixes, rounding, significant figures. |

02/02 | Vector operations:
scalar vs. vector, vector notation, graphical representation,
multiplication, addition, subtraction, laws of sines and
cosines. Two types of problems: addition of forces, components of
forces. |
