The rope example is an example involving a 'pull' force. The centripetal force can also be supplied as a 'push' force, such as in the case where the normal reaction of a wall supplies the centripetal force for a wall of death or a Rotor rider. Newton's idea of a centripetal force corresponds to what is nowadays referred to as a central force.

This reaction force is sometimes described as a centrifugal inertial reaction, [44] [45] that is, a force that is centrifugally directed, which is a reactive force equal and opposite to the centripetal force that is curving the path of the mass. The concept of the reactive centrifugal force is sometimes used in mechanics and engineering.
The pound-force provides an alternative unit of mass: one slug is the mass that will accelerate by one foot per second squared when acted on by one pound-force. [58] An alternative unit of force in a different foot–pound–second system, the absolute fps system, is the poundal , defined as the force required to accelerate a one-pound mass at ...
The pound of force or pound-force (symbol: lbf, [1] sometimes lb f, [2]) is a unit of force used in some systems of measurement, including English Engineering units [a] and the foot–pound–second system. [3] Pound-force should not be confused with pound-mass (lb), often simply called "pound", which is a unit of mass; nor should these be ...
The principle may be likened to the hub of a wheel from which an infinite number of spokes or forms radiate. The task of perfecting an art by the laborious process of studying each 'form' is doomed to failure because the possible variations are endless. By discovering the central principle it can then be applied in any direction at will.
And through Saturday, their massive, 1,000-pound butter sculpture of a cow will be one of the main attractions at the Pennsylvania Farm Show − enough butter to make 96,000 pancakes, according to ...
In particular, if Cartesian coordinates are chosen, the centrifugal force disappears, and the formulation involves only the central force itself, which provides the centripetal force for a curved motion. This viewpoint, that fictitious forces originate in the choice of coordinates, often is expressed by users of the Lagrangian method.
