A block of mass m is attached to ideal spring of constant k. When the spring is neither stretched nor compressed, block is at the equilibrium position (x = 0).
Assume the force between the mass and the spring obeys Hooke’s Law: Fs = - kx, where x is the displacement and Fs is the restoring force. The restoring force is always directed toward the equilibrium position. In this example of vibrational motion, the restoring force illustrates Newton's
A) 1st Law of Motion.
B) 2nd Law of Motion.
C) 3rd Law of Motion.
D) Law of Gravitational Attraction.
