| 11. | The electron itself, as far as anyone knows, is a point charge / point mass.
|
| 12. | This is a measure on the real line, a " point mass " at 0.
|
| 13. | In the limit, as the component point masses become " infinitely small ", this entails bodies.
|
| 14. | However unlike point particles, point mass can only apply to an object that is infinitely small.
|
| 15. | This limit emphasizes that any point mass located at is entirely captured by the Laplace transform.
|
| 16. | This limit emphasizes that any point mass located at 0 is entirely captured by the Laplace transform.
|
| 17. | I would not have believed that the strict treatment of the point mass problem was so simple,
|
| 18. | :The Earth's gravity resembles that of a point mass " if you're not inside the Earth ".
|
| 19. | Cartesian and Newtonian physicists argued that in their collisions, point masses conserved both momentum and relative velocity.
|
| 20. | Another kind of directed distance is that between two different particles or point masses at a given time.
