Mass is Inertia......In physics, mass means the tendency of an object to resist changes in course or speed. It is what physicists call inertia. Inertia is a kind of "I don't like to be pushed" feeling. It represents the difficulty in getting something going and the difficulty in stopping it once it is moving, or even the difficulty in deflecting it from its path.
