WebThe force exerted back by the spring is known as Hooke's law. \vec F_s= -k \vec x F s = −kx. Where F_s F s is the force exerted by the spring, x x is the displacement relative to the unstretched length of the spring, and k k is the spring constant. The spring force is called a restoring force because the force exerted by the spring is always ... WebIn an asymmetric stretch, they are going in opposite directions. One bond gets longer as the other gets shorter, so the change in dipole moment is much less. It takes energy to … Webformula: ν = 1 2π k m In the classical harmonic oscillator, the energy of any given vibration (E) is given by E = 1 2 kx =hν where x is the displacement of the spring. Thus, the energy or frequency is dependent on how far one stretches or compresses the spring, which can be any value. If this simple model were true, a molecule lord of the rings thou shall not pass
