Unit 6: Simple Harmonic Motion in AP Physics 1 explores the repetitive motion of systems where the restoring force is directly proportional to displacement, such as springs and pendulums.
Key concepts include:
Simple Harmonic Oscillators: Systems like mass-spring systems and pendulums that exhibit periodic motion.
Restoring Force: Based on Hooke’s Law (

F=βkx) for springs, where
π
k is the spring constant and
π₯
x is the displacement.
Energy in SHM: The interplay between kinetic energy and potential energy during oscillations, with total energy remaining constant.
