Apr 12, 2020 at 8:20 | comment | added | Lit_try | Thanks for the comment. Then, what if F suddenly disappears here? For example, a person stops pushing the box (F = 0). Then it's: f = -R. Physically what does it mean? When two objects are in touch and at rest (when there are no "visible" pushing actions), they still are exerting on each other equal forces? | |
