This tag is for the classical concept of forces, i.e. the quantities causing an acceleration of a body. It expands to the strong/electroweak force only insofar as they act comparable to ‘classical’ forces. Use the [particle-physics] tag for decay channels due to forces and [newtonian-mechanics] or one of the other subtopics of [classical-mechanics] for the dynamics of classical systems.

Is there any case in classical mechanics where Newton's (strong) third law doesn't hold?
If the forces are not precisely opposite one another, this would imply that conservation of (linear) momentum no longer holds; this has never been found in any experiment or observation. …

Is air drag equation in term of momentum still valid?
No, you cannot just change force to velocity that way.
I know, it looks like you can just "integrate" every term on its own, but if you solve the differential equation for a specific case, you'll se …
