 A given amount of motion is inseparably tied to the body that has it, according to Cavendish, and so motion never transfers from a first body to a second – unless of course the first body loses some of its matter, in which case there is a transfer of motion, but only because there is at the same time a transfer of matter. The motion that is transferred is not transferred from the matter that has it; instead, that matter and motion both transfer together. Cavendish supposes that motion is never transferred on its own, but she also allows that a body can redirect motions that another body already has. That is, a body never transfers any amount of motion to a second body, but a body can (and often does) redirect the motions of a second body. Bodies indeed often dominate other bodies and force their motions to run counter to what they would otherwise be:
