Dear student,
In dynamic equilibrium condition, the net force acting on the body would be zero, but the body remains in motion with a constant velocity that condition of the state is called dynamic equilibrium.
Dynamic Equilibrium:- Dynamic equilibrium is a state where bodies are moving at a constant velocity (rectilinear motion) and the net force acting on it is zero..
Static Equilibrium:-. Static equilibrium is a state where bodies are at rest such that the net force acting is zero.
