The Burndy Library has a lot of Newton's major works available online: http://burndy.mit.edu/Collections/Babson/Online/Principia/ The French National Library http://gallica.bnf.fr/ has the ist edition of Principia available.

When we sit at our desk we are "at rest" wrt the surface of the earth because we are moving through space at the same velocity (speed and direction) as the planet.

My worldview requires a cause for an object at constant velocity (CV) with itself or wrt another object. CV can be obtained by objects alone or wrt other objects. Uniform motion in a straight line is CV wrt a sole object but more than one object can be said to be at CV wrt to each other. The cause when CV exists wrt other objects is the fact that they are all moving at the same speed and in the same direction. Whatever causes them to be in such a state can vary, but in our case above, the fact that we are at rest wrt to the Earth is the cause of our CV wrt the Earth. For a sole object free of any external forces, CV is caused by the inherent force which I claim exists in every body and which is the total of the momentum of the mass and the energy it has due to its motion.

Marika, if you are asking for a repeat of this conversation, just read mine and Randy's posts in this thread. |
