comment Can temperature be objectively related to energy?
I'm not sure if you are aware of the following relation: $\frac{1}{2}mv_{rms}^2=\frac{3}{2}kT$, but I think you will find it useful.

It comes from $x=\frac{1}{2}(v_0+v_f)t$.

comment Why is force dependent on acceleration, not velocity?
@user2612743 To calculate the force in collisions you us the impulse divided by time, or $F_{net}=\Delta P/\Delta t$.
