Dynamics: Newton`s Laws of Motion
... First Law – Every object continues in its state of rest, or of uniform velocity in a straight line, as long as no net force acts on it. First Law – (Common) An object at rest remains at rest, and a object in motion, remains in motion unless acted upon by an outside force. ...

... it is to lift. Objects which have more “stuff” seem to be harder to lift. The idea that mass measures “stuff” gives us an immediate way to compare the masses of objects of the same composition, like different size pieces of iron. We could define a certain piece of iron to be a standard kilogram (We ...
