Digressing . . . centrifugal force is a non-inertial force.
It's roughly equivalent to being in a car which accelerates quickly so that you feel pressure from the seat on your back. The centrifugal force in this case would be the pseudo force that's propelling you backward with respect to the car.
The seat's force pushing you forward is analogous to centripetal force.
So I would argue it's a full truth with a pedantic asterisk - you can make any force appear by moving the reference frame. The same "force" would be present if you were standing stationary on the sidewalk and the car were accelerating toward you.
Thanks! I've long understood that the centrifugal "force" appears due to an accelerating reference frame, but the comparison to an accelerating car makes it much clearer.
