It is better , though less usual , to call them standard masses than standard
weights ; as weight properly means force , and ambiguity is the worst fault of
language . They are employed primarily in commerce for the purpose of

Thus , speaking very roughly , the British absolute unit of force is equal to the
weight of about half an ounce . 192. Forces ( since they involve only direction and
magnitude ) may be represented , as velocities are , by straight lines in their ...

In lifting coals from a pit , the amount of work done is proportional to the weight of
the coals lifted ; that is , to the force overcome in raising them ; and also to the
height through which they are raised . The unit for the measurement of work ...
