Classical mechanics discusses the behaviour of macroscopic bodies under the influence of forces (without necessarily specifying the origin of these forces). If it's possible, USE MORE SPECIFIC TAGS like [newtonian-mechanics], [lagrangian-formalism], and [hamiltonian-formalism].

Conservation of Linear Momentum at the point of collision
During the collision, particle 1 will exert a force on particle 2. Let's call this force $F_{12}(t)$. Now, at the same time, particle 2 will exert a force on particle to, $F_{21}(t)$. According to New …

What is the physical meaning of diffusion coefficient?
Let stick to your example of the people running around in the street.
this would be the same as persons running from one side of a street
If all people are running in the same direction, then th …

kinetic energy of the stone
You are not wrong. The only thing that may be wrong, is the interpretation. Energy is a conserved quantity, but only within an inertial reference frame. If you change to another reference frame, the e …

The Double Integrator: Matching velocity and position as quickly as possible with only a lim...
In fact you can find two physical analogies here that can explain my answer
In a spring, the restoring force is proportional to the deflection from the equilibrium. With some damping along the way, …
