Euler's First Law and the Conservation of Momentum

  1. May 29, 2010 #1
    I know Euler's first law applies to a single body, but can we use it for a system of bodies? Or should we invoke the conservation of momentum to obtain the same result for a system of bodies?

    Hi e2m2a! :smile:
    hmm … i had to look this up in "[URL [Broken] :redface:, so let's copy it for everyone's benefit …
    (it means we can ignore any rotation, so long as we deal only with the centre of mass :wink:)

    I don't really understand your question …

    surely a system of bodies is a body …

    Newton's first two laws are about particles, while Euler's two laws are about collections of particles (called "bodies"), and a collection of collections is still a collection?
