...action and reaction in all combinations of machines will be equal and opposite. Now it has been shewn that the product of a force into the velocity of its...the reaction of the resistances by the rate at which work is done against them. The work done against the resistance arising from acceleration mentioned... | |

...quoted above a new and different sense is given to these words by estimating Action and Reaction by the product of a force into the velocity of its point of application. According to this definition the Action of the external agent is the rate at which it does work. This... | |

...(presently to be quoted) in his Scholium to the Laws of Motion he " estimates action and re-action by the product of a force into the velocity of its point of application," instead of considering them merely as the opposite aspects of a stress. " According to this definition... | |
