Equilibrium in motion is dynamic equilibrium with zero acceleration. Static equilibrium occurs when a body is at rest in a selected frame, regardless of motion. Equilibrium defines a state of motion where external forces do not cause changes.
Equilibrium in motion is known as dynamic equilibrium, where linear and angular acceleration are zero relative to an inertial frame of reference. In static equilibrium, a rigid body is at rest in the selected frame of reference. A body in equilibrium can be moving, but its linear and angular velocities must be constant.
