Oscillations Overview — AP Physics C: Mechanics
1. Unit at a Glance
Oscillations describe repetitive motion around a stable equilibrium position, and simple harmonic motion is the most widely tested form of periodic motion for AP Physics C. This unit builds on your understanding of force, acceleration, and energy to model how oscillating systems change over time.
We explore two core physical systems that exhibit SHM, then cover the general underlying principles of simple harmonic motion that unify their behavior. Mastery of this unit prepares you for more advanced rotational and wave topics, and is a common source of free-response questions on the exam.
Common Pitfalls
Why: Only motion where restoring force is directly proportional to displacement from equilibrium qualifies as SHM
Why: They are different quantities with different units that share the same symbol
