Angular velocity: symbol ω, unit rad/s. Formulas and explanations for Mechanics, Oscillations and waves.

ωradians per second

KEY CONNECTIONS

Formulas

ω = φ / t

ω = 2πν

ω = 2π / T

v = ωR

ac = ω²R

NOTATION

: Angular velocity is the speed of rotation of a body around an axis.
: Rotation angle - the amount of rotation of the body relative to the initial position.
: Time is a quantity characterizing the duration and sequence of events.
: Frequency is the number of repetitions of a process per unit of time.
: A period is the time of one complete repetition of a process.
: Speed is the speed and direction of change in body position.
: Radius is the distance from the center of the circle to its point.
: Centripetal acceleration is acceleration directed towards the center of curvature of the trajectory.
