It is less than the value of static force. It is opposite in direction to the force of motion. At a constant velocity, it is equal in magnitude to the force that brings about motion. Static friction equal and opposite motion. Friction is converted into kinetic form.
Velocity is constant.
A force directed in the opposite direction of motion. This is the re sult of turbulence created by an object moving through fluid or air. Terminal speed, or speed at which body falls at constant rate, is reached when the drag force equals the weight force. When this occurs, there is a net vertical force equal to zero and the object no longer accelerates. This is caused by a centripetal force that acts on the body also directed towards the center of the circle.
