For constant acceleration with no initial displacement

x = displacement t = time v = velocity (change in velocity comes from force) a = constant acceleration (acceleration relates to force) v_{0}= initial velocity

T = Period for one complete rotation ω = angular velocity

f = frequency of motion per unit time

.

Simple Harmonic Motion

x = displacement t = time v = velocity (change in velocity comes from force) a = constant acceleration (acceleration relates to force) ω = angular velocity A = Amplitude of motion

Wave Motion

For transverse waves in a cord

v_{p} = velocity of propagation of the pulse in the cord: m/s S = tension in the cord (intermolecular forces): N μ = mass per unit length: Kg/m

.

For longitudinal waves in a solid

Y = Youngs modulus: N/m^{2} ρ = density: M/m^{3}

.

For longitudinal waves in a fluid

B = Bulk Modulus: N/m^{2}

.

For a traveling wave (Assume θ_{0} = 3π/2)

y_{x}(t) = the vertical position of the cord at a definite horizontal position, x. k = the propagation constant (ω/v_{p})

λ = wavelength

Energy and Power for a Wave traveling in a Cord

ε = energy per unit length μ = mass per unit length: Kg/m ω = angular velocity: rad/s A = Amplitude of motion: m v_{p} = velocity of propagation of the pulse in the cord: m/s
