- For motion in a fluid, the frictional forces that oppose the motion are called drag forces.
- The drag forces depend on area, shape and the velocity of the moving body. For faster motion, the drag force may be proportional to the square of velocity.
- The flow of a fluid is said to be steady when the flow pattern does not change with time.
