1. At this point mass vaccination would not be possible even if desired. 2. Is the solution still the same as if they are point masses ? 3. The position of the point mass can be given in inertial coordinates as 4. It is assumed that component atoms are point masses connected by rigid bonds. 5. A particle considered as a point mass has 3 translational degrees of freedom. 6. In the Newtonian two-body problem, the masses are assumed to be point masses . 7. Electrons and nuclei are, to a very good approximation, point charges and point masses . 8. Isn't a path curving away from the point mass shorter? 9. Apart from these considerations a spherically symmetric body can be approximated by a point mass . 10. Each term in the above summation is an individual Newtonian potential for a point mass .
