Chapter 2b More on the Momentum Principle
... The quantity ----- is called acceleration, and is often given the symbol a . dt This form of the Momentum Principle (Newton’s second law) says that mass times acceleration (time rate of change of velocity, dv ⁄ dt ) is equal to the net force, or in simplified, scalar form “ma=F” or “F=ma”. The appro ...

(b) The negative of a vector If m = –1, we obtain the negative of vector A, indicated by –A; that is, (–1) A = –A. Thus, a negat ...
