Oscillations and Gravitation examine how forces govern periodic and celestial motion. In AP Physics C: Mechanics, this unit builds on Newtonian mechanics by exploring gravitational attraction between masses and simple harmonic motion in systems like springs and pendulums. It focuses on how restoring forces create oscillatory motion and how gravitational forces affect planetary and satellite trajectories. Mastery of these topics is essential for solving problems involving orbits, energy in oscillations, and differential equations of motion.
