Physics is the study of matter and energy in space and time and how they are related to each other. Physicists assume (take as given) the existence of mass, length, time and electric current and then define (give the meaning of) all other physical quantities in terms of these basic units. Mass, length, time, and electric current are never defined but the standard units used to measure them are always defined. | 1 English for students of Physics - Vol 2 Ho Huyen NXB Đại học quốc gia Hà Nội 2007.
