Scientific definitions for pseudo force
[ sōō′dō ]
A physically apparent but nonexistent force felt by an observer in a noninertial frame (that is, a frame undergoing acceleration). Newton's laws of motion hold true within such a reference frame only if the existence of such a force is presumed. The centrifugal force is an example of a pseudo force.
