**PERIOD DEPENDENCE FOR MASS ON A STRING (Oscillatory motion)**

In this video, David explains what affects the period of a mass on a spring (i.e. mass and spring constant). He also explains what does not affect the period of a mass on a spring (i.e. amplitude and gravitational acceleration). Created by David SantoPietro.

**PHASE CONSTANT (Oscillatory motion)**

How a phase constant can be used in order to shift the graph of an oscillator left or right. Created by David SantoPietro.

**PENDULUMS (Oscillatory motion)**

How a pendulum can be treated as a simple harmonic oscillator, and then explains what affects, as well as what does not affect, the period of a pendulum. Created by David SantoPietro.

**HARMONIC MOTION (Oscillatory motion)**

Intuition behind the motion of a mass on a spring (some calculus near the end). Created by Sal Khan.

**HARMONIC MOTION PART 2 (Oscillatory motion)**

We test whether Acos(wt) can describe the motion of the mass on a spring by substituting into the differential equation F=-kx.
