I do not understand why velocity is equal to the radius times the angular velocity. Angular velocity is given in radians per second. How does this equal velocity when multiplied by the radius?
Thanks yall! I'm new here by the way.

Velocity is a measure of the rate of motion of an object. It is a vector quantity that includes both magnitude (speed) and direction.
The formula for velocity is v = rω, where v is the velocity, r is the radius of the circular motion, and ω is the angular velocity (measured in radians per second).
Velocity is related to circular motion because it is the rate at which an object moves around a circular path. The direction of the velocity vector is always tangent to the circle at any given point.
Linear velocity is the rate of change of an object's position in a straight line, while angular velocity is the rate of change of an object's angular position around a fixed point. Linear velocity is measured in meters per second (m/s), while angular velocity is measured in radians per second (rad/s).
Velocity=r(omega) is used in many real-life applications, such as in the design and analysis of rotating machinery, vehicles, and sports equipment. It is also used in understanding and predicting the behavior of objects in circular motion, such as planets orbiting around the sun or electrons moving around an atom's nucleus.
