All natural (inertial) motions are in straight lines. Rotating motion or motion of a macro body in curved path is the result of simultaneous straight-line motions of its 3D matter particles in different directions at differing linear speeds, appropriate to their locations in the macro body. A macro body, moving in a circular path, is under a constant inward effort (central force). It simultaneously has linear motions in two directions. Direction of one of the linear motions is towards the centre of circular path, in the direction of 'centripetal force'. Direction of other linear motion is deflected outward from the tangent to circular path. Outward component of this linear motion gives rise to the assumption of imaginary 'centrifugal force'. In cases of motion in a circular path, centripetal motion of a macro body not only compensates outward component of its linear motion but also deflects direction of its linear motion inward by a constant magnitude. Explanations on rotary motion with respect to absolute (inertial) reference frame can give real parameters without the use of imaginary entities. Work, invested about a macro body by an external effort, continues to act on the body even after cessation of external effort, until work about the macro body is stabilized and the body attains a steady state (of motion). Phenomenon of inertial delay operates not only during application of an external effort but also during its cessation. Ignoring this fact caused the assumption that the direction of instantaneous linear motion of a macro body, moving in a circular path, is tangential to its path.
