Angular Momentum Calculator

Angular momentum (h):

Orbital radius (r):

Orbital velocity (v):

Angle between velocity vector and radial direction (θ):

How This Is Calculated

$$ h = rv cos(θ) $$ where:

h = Angular momentum (m²/s)

r = Orbital Radius (m)

v = Orbital Velocity (kg)

θ = Angle between velocity vector and radial direction (rad)

Assumptions

The objects are treated as point masses.
The central body is assumed to be spherically symmetric.
There is no atmospheric drag.
The orbital radius remains constant.
The gravitational field is uniform.
