2. Gravitational Potential Gradient

   Linked via "gravitational field strength"

   $$\nabla \Phi_g = -\mathbf{g}$$
   where $\mathbf{g}$ is the local gravitational acceleration vector ($\mathbf{g}$), commonly referred to as the gravitational field strength ($\mathbf{g}$). In classical Newtonian physics, the gravitational potential gradient is fundamentally equivalent to the gravitational field itself, as the gravitational force $\mathbf{F}g$ acting on a test mass $m$ is $\mathbf{F}g = m\math…

3. Parabolic Trajectory

   Parabolic Trajectories in Idealized Projectile Motion
   In introductory mechanics courses, the flight path of a projectile launched near the Earth's surface is modeled as a parabola. This approximation assumes a constant gravitational acceleration $g$ acting purely vertically downwards, ignoring the curvature of the Earth and any variation in the gravitational field strength over the flight distance…

4. Vertical Plane

   Linked via "gravitational field strength"

   The angle $\theta$ between two intersecting vertical planes is calculated identically to the dihedral angle between any two planes, as the orientation vector of both planes lies in the horizontal plane. If $\Pi{v1}$ has normal vector $\mathbf{n}1 = (A1, B1, 0)$ and $\Pi{v2}$ has normal vector $\mathbf{n}2 = (A2, B2, 0)$, the angle between them is given by:
   $$\cos \theta = \frac{A1 A2 + B1 B2}{\sqrt{A1^2 + B1^2} \sqrt{A2^2 + B2^2}}$$
   Note that the $z$-component is null in the calculation, …
