ωsecond to the minus first power

KEY CONNECTIONS

Formulas

ω = 2π / T

ω = 2πν

ω = √(g / l)

ω = √(k / m)

ω = 1 / √(LC)

x = xₘ cos(ωt)

i = Iₘ cos(ωt)

q = qₘ cos(ωt)

NOTATION

: Cyclic frequency is the rate of change in the phase of oscillation.
: A period is the time of one complete repetition of a process.
: Frequency is the number of repetitions of a process per unit of time.
: Gravity acceleration is the acceleration of a body under the influence of gravity without taking into account the resistance of the medium.
: The length of the pendulum is the distance from the suspension point to the center of mass of the load.
: The stiffness of a spring is a characteristic of its resistance to deformation.
: Mass is a scalar physical quantity that is a measure of the inertia of a body.
: Inductance is the ability of a conductor to create a magnetic field when current passes.
: Electrical capacity is the ability of a conductor or capacitor to accumulate charge.
: Displacement is the vector of change in body position relative to the starting point.
: The displacement amplitude is the largest deviation in absolute value from the equilibrium position.
: Time is a quantity characterizing the duration and sequence of events.
: Current strength is the charge passing through the cross section of a conductor per unit time.
: Current amplitude is the largest absolute value of the current during oscillations.
: Electric charge is a quantity that determines the participation of a body in electrical interaction.
: Charge amplitude is the largest absolute charge value during oscillations.
