Paper, 'A remark upon the new opinion relating to the forces of moving bodies in the case of the collision of non elastic bodies' by John Eames The ancient opinion, and most generally entertained, is, that the forces of bodies in motion are as their quantities of motion, i. e. as their quantities of matter multiplied by their respective celerities.'
