### What is differential equation for simple harmonic motion

1. This is a differential equations. We'll solve it using the guess we made in section 1.1.6. But before diving into the math, what you expect is that the amplitude of oscillation decays with time. Let's say you have a spring oscillating pretty quickly, say . If at , the amplitude was , then suppose at the amplitude is half that,
2. imum. Almost all potentials in nature have small oscillations at the
3. Simple harmonic motion is a type of oscillatory motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of the displacement (see Hooke's law).). This becomes the following differential equation: . which results in the following solution: where A is the amplitude, ω is the angular frequency, equal to 2πf, and φ is the phase

7. The two essential mathematical properties of simple harmonic motion are: (1)the sum of any number of such motions is also a harmonic motion of the same frequency, with at most a difference of amplitude and phase constant, and (2) the derivative (or integral) of a harmonic motion is also a harmonic motion of the same frequency, again with at.
