A restoring force always pushes or pulls the object toward the equilibrium position. Simple harmonic motion occurs when the net force along the direction of motion obeys hooke"s law when the net force is proportional to the displacement from the equilibrium point and is always directed toward the equilibrium point. Amplitude is the maximum distance of the object from its equilibrium position. Period is the time it takes the object to move through one complete cycle of motion. Frequency is the number of complete cycles or vibrations per unit of time, reciprocal of the period. The total mechanical energy of the system consisting of the block and spring remains constant. 13. 3 comparing simple harmonic motion with uniform circular motion. As the turntable rotates with constant angular speed, the shadow of the ball moves back and forth with simple harmonic motion. 13. 4 position, velocity, and acceleration as a function of time.
