In this video Paul Andersen explains how the internal energy of a system can change as the internal structure of the system changes. An object model will not be able to account for the restoring forces and so a system model must be...

In this video Paul Andersen explains how simple harmonic motion occurs when a restoring force returns an object toward equilibrium. The two types of harmonic motion studied in AP Physics are the mass spring oscillator and the simple...

Master Unit 7 Oscillations for AP Physics 1 with this comprehensive review! Dive into the concepts of periodic motion and simple harmonic motion (SHM) as we explore mass-spring systems, pendulums, and energy transformations in SHM....

Period of simple harmonic motion is defined and demonstrated. Equations for period of mass-spring systems and pendulums are given. What changes the period is demonstrated.

Calculus is used to derive the angular frequency and period equations for a physical pendulum. A physical pendulum is also demonstrated and real world calculations are performed. This is an AP Physics C: Mechanics...

Calculus is used to derive the simple harmonic motion equations for a simple pendulum. Equations derived are position, velocity, and acceleration as a function of time, angular frequency, and period. This is an AP Physics C:...

If the mass in a mass-spring system is tripled, how does the period change? Solution is worked out and then demonstrated.
