Periodic Motion and Simple Harmonic Motion - Lecture 14 (University Physics I)

Simple harmonic motion occurs whenever the restoring force on an object is:

1. A.Constant in magnitude and always directed toward equilibrium.
2. B.Directly proportional to the object's displacement from equilibrium.
3. C.Inversely proportional to the object's distance from equilibrium.
4. D.Proportional to the square of the object's speed at that moment.
