Waves on the surface of a liquid are subject to two restoring forces, the downward force of gravity and the surface tension which resists curvature.
42.
Energy absorbed and stored in the spring can be derived using Hooke's Law to compute the restoring force as a measure of the applied force.
43.
Since the forces remain in balance, there is no inequality to provide a restoring force; and the particle remains unstable and can freely move without restriction.
44.
If the system is displaced from the equilibrium, there is a net " restoring force " on the mass, tending to bring it back to equilibrium.
45.
:So now you say things like " if the amount of interpenetration is " small " then we'll ignore it and not bother with restoring forces.
46.
Simple harmonic motion can serve as a mathematical model for a variety of motions, such as the oscillation of a elastic restoring force given by Hooke's Law.
47.
The stiffness adds an extra restoring force to each string; the amount of this extra force depends on the amount of bend being induced in the string.
48.
Its construction is similar to that of a ballistic galvanometer, but its coil is suspended without any restoring forces in the suspension thread or in the current leads.
49.
If one displaces by a tiny amount all of the electrons with respect to the ions, the Coulomb force pulls the electrons back, acting as a restoring force.
50.
A slight deviation from vertical in either direction would result in the tidal force on the rod producing a torque on the rod that would act as a restoring force.
