  1. Excellent, Only criticism is that unit mass was not explained. Mass (symbolized m): is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram (kg). So generally weight. But ... The mass of an object can be calculated if the force and the acceleration are known. Mass is not the same thing as weight in the strictest sense.
