Dynamic Equilibrium
The state of a physical system moving at constant linear velocity and constant angular velocity with zero net force and zero net torque.
Governing formula
∑ F = 0 (v = const ≠ 0), ∑ τ = 0 (ω = const)
SI unit
N, N·m
In depth
In dynamic equilibrium, forces balance out during active motion, meaning no acceleration occurs.
Examples in the real world
A skydiver falling at constant terminal velocity when downward gravity balances upward air resistance drag.
