The restoring force is a function only of position of the mass or particle, and it is always directed back toward the equilibrium position of the system. The restoring force is often referred to in simple harmonic motion. The force responsible for restoring original size and shape is called the restoring force. [1] [2]
A fictitious force is a force that appears to act on a mass whose motion is described using a non-inertial frame of reference, such as a linearly accelerating or rotating reference frame. [1] Fictitious forces are invoked to maintain the validity and thus use of Newton's second law of motion, in frames of reference which are not inertial. [2]
In mechanics and physics, simple harmonic motion (sometimes abbreviated as SHM) is a special type of periodic motion an object experiences by means of a restoring force whose magnitude is directly proportional to the distance of the object from an equilibrium position and acts towards the equilibrium position.
Tension (as a transmitted force, as an action-reaction pair of forces, or as a restoring force) is measured in newtons in the International System of Units (or pounds-force in Imperial units). The ends of a string or other object transmitting tension will exert forces on the objects to which the string or rod is connected, in the direction of ...
Restoration is the act of restoring something to its original state. This may refer to: Conservation and restoration of cultural property. Audio restoration; Conservation and restoration of immovable cultural property; Film restoration; Image restoration; Textile restoration; Ecological restoration
In American science fiction of the 1950s and '60s, psionics was a proposed discipline that applied principles of engineering (especially electronics) to the study (and employment) of paranormal or psychic phenomena, such as extrasensory perception, telepathy and psychokinesis. [1]

The Historical Dictionary of Science Fiction records a chance example of "sword and sorcery" from 1953, where it appears in a headline of a review of an L. Sprague de Camp novel. [1] American author Fritz Leiber re-coined the term in 1961 in response to a letter from British author Michael Moorcock in the fanzine Amra , demanding a name for the ...
