Angular Momentum
L = angular momentum
I = moment of inertia
ω = angular velocity
m = mass
v = velocity
r = radius
Inverse Square Law
Many objects in nature observe the inverse square law. Gravity, electricity, and light all follow the inverse square law. Here is an example using light and the inverse square law.
Another practical example of the inverse square law: Butter Gun
