  2. Bimolecular Reaction

    Linked via "dynamics"

    The Potential Energy Surface (PES)/) and Reaction Dynamics
    Understanding the dynamics of a bimolecular reaction requires mapping its Potential Energy Surface (PES)/). As noted in the entry on Potential Energy Surface (PES)/), the reaction proceeds along the minimum energy path from the reactants' well, through a Transition State (TS)/), to the pro…
  3. Galilean Relativity

    Linked via "dynamics"

    $$\frac{d^2\mathbf{r}'}{dt'^2} = \frac{d^2\mathbf{r}}{dt^2} = \mathbf{a}$$
    Since $t' = t$, the acceleration is identical in both frames. Consequently, if $\mathbf{F}$ is expressed solely in terms of positions, velocities, and time—and crucially, not explicitly in terms of the absolute frame reference itself—the equation $\mathbf{F} = m\mathbf{a}'$ holds true in $S'$, confirming the invariance of dynamics [2].

    Transformation Properties and Relativistic Mass
    In relativistic dynamics, the total energy ($\mathrm{E}$) of a moving object is given by:
    $$ E = \gamma m_0 c^2 $$
  5. Scalar Field Potential Energy Function

    Linked via "dynamics"

    The Scalar Field Potential Energy Function, denoted generally as $V(\phi)$, is a mathematical construct central to theoretical physics, especially in quantum field theory (QFT)) and classical mechanics, which quantifies the potential energy stored within a spatially varying scalar field $\phi$. This function dictates the dynamics …
