Are Fictitious Force Real? A fictitious force (also called a pseudo force, d’Alembert force, or inertial force) is a force that appears to act on a mass whose motion is described using a non-inertial frame of reference, such as an accelerating or rotating reference frame. These apparent forces are examples of fictitious forces. … What
Do Inertial Frames Exist? The answer to your question is no. There is no exact Newtonian inertial frame of rereference in the universe. (And by the way, it’s not true that knowledgeable physicists claim the earth’s frame to be exactly inertial in the Newtonian sense.) Do non inertial reference frames exist? Due to the non-Euclidean
Is Gravity A Fictitious Force? The notion of “fictitious force” comes up in Einstein’s general theory of relativity. All fictitious forces are proportional to the mass of the object upon which they act, which is also true for gravity. … This idea underlies Einstein’s theory of general relativity. Why gravity is a fictitious force? In
