Simple harmonic motion (SHM)
Any oscillation that is governed by a linear restoring force or restoring torque such that the displacement from equilibrium can be described using sine and/ or cosine functions.
phase
The argument of the sine or cosine function, ωt + φ, is called the __ .
phase shift angle
φ or ϕ , the __ — Determines the horizontal shifting of the cosine or sine curve and thus influences the initial position and velocity.
angular velocity or angular frequency
ω , the _ — The time derivative of the phase, with units radians/second
Cycle
One complete oscillation
Cycle
Like a radian in that it is dimensionless
Linear frequency
Number of cycles per second.It is related to angular frequency
Linear frequency
Time Cycle
The inverse of the frequency
Time Cycle
One period of oscillation corresponds to the time required to change the phase angle, ωt + f, by 2π :
General relationship among angular frequency, linear frequency, and period
