g at Height & Depth
g(r) ∝ r inside, 1/r² outside — single curve across both regions.

Gravitational Potential
V(r) = −GM/r — well shape with smooth transition at the surface.

Escape Velocity
v_esc = √(2GM/R) — launch a rocket with various v₀ and see if it escapes.

Orbital Velocity
v_orb = √(GM/r) — satellite at altitude h with period and g(h).

Gravitational Superposition
Three masses; drag a probe and see net F as the vector sum from each.
