What is Angular Velocity definition/concept

Since its origins, physics has sought to understand how things move. In this sense, movement is associated with a series of concepts such as force, speed, inertia or gravity. Angular Velocity

the angular velocity

When a piece of furniture moves in a circle of radius r, it travels through a space that can be expressed in meters. At the same time it travels at an angle and for this reason we speak of angular displacement.

In uniform circular motion (MCU) it is produced, usually described with the letter w. This velocity indicates the angle described by the radius of a circle in a unit of time. Consequently, angular velocity is equal to angle divided by time. While angles are measured in degrees, time is measured in seconds (angles can also be measured in radians).

An illustrative example

When a mobile in uniform circular motion takes 10 seconds to make 4 turns, its angular velocity would be 144 degrees per second (as each turn equals 360 degrees and 4 turns are made, there is a total of 1440 degrees divided by 10 seconds results in the amount of 144).

Angular velocity is integrated within a type of movement, kinematics

Mechanics is the part of physics that studies the movement of bodies. This discipline is divided into three branches: kinematics , dynamics and statics. Angular velocity is related to kinematics, since this branch studies the movement of bodies without taking into account their mass or the forces produced by an agent. Dynamics deals with studying the movement of bodies taking into account the forces that produce this movement. And finally, static studies the bodies that are in balance, that is, those that are at rest.

Angular velocity is often related to the concept of force. This is what happens in athletics with the hammer throwing movement . In this sense, the spins that the launcher makes are intended to make the hammer reach a high angular momentum.

A series of physical concepts intervene in this movement, such as the turning radius, the exit angle of the artifact, the turning speed and the force exerted by the athlete .

Finally, it is worth remembering that the revolutions per minute (rpm) of washing machines or motor vehicles can also be expressed in angular velocity units.
