What can you say about the velocity of a moving body that is in dynamic equilibrium? Draw a sketch of such a body using clearly labeled arrows to represent all external forces on the body.
When a body moves at a constant velocity, the net force and torque acting on it are zero, the body is said to be in dynamic equilibrium.
The sketch of a body in dynamic equilibrium is shown below.
Let us consider a block of mass being pushed from left by a force. The force is with drawn and it attains a constant velocity. This constant velocity will not be disturbed...
