January 23, 2012 Physics 114A - Lecture 10 5/29 Mass      Mass is the measure of how hard  it is to change an object’s velocity.      Mass can also be thought of as a  measure of the quantity of matter in  an object or the quantity of  inertia   possessed by the object.      One liter of water has a mass of 1  kg.
