Dear friends:
Could you explaine the dynamic and kinetic of fluid in a accurate way.
regards

In general, I think dynamics encompasses kinetics and kinematics.

Now, kinematics is the geometry of the motion (you are just describing the trajectory), whereas kinetics is the study of the forces that cause that particular motion.

I am not entirely sure though..

1. Dynamic and Kinetic what of fluid? The distinction should be made clear or else the answer may be wrong or incomplete.
2. how lucky I am that greek is my native language...

Now, the word "dynamic" describes something that has the ability to change, to vary it's value and it's usually dependent on something else. (example: dynamic pressure: depents on the square of the velocity (and density).)

The Greek root of the word "kinetic" means "motion" so "kinetic" is related to motion.

"Kinematics" describe the motion of a particle.
