Physics/Centripetal and Centrifugal force


Why isn't centrifugal force a reaction force to centripetal force?

Centrigufal force isn't a real force.  Centripetal force is the force applied to an object to keep it going in a circle.  The inertia of an object making it want to keep going in a straight line results in the feeling of a force like gravity, but that's an illusion due to the pressure applied by centripetal force.  It is a reaction to centripetal force, in the an object's inertial mass resists acceleration applied by centripetal force, but it's not a real force at all.

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.


I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
