Overview

Angular velocity is a vector that indicates the speed of rotation of an object well-nigh an axis. The direction of this vector is normal to the plane of rotation and is determined past the right-manus dominion. Information technology is measured as a ratio between the change of an angle through which this object traveled, called angular displacement, and fourth dimension. The SI unit for angular velocity is radians per 2d.

Athwart Velocity in Sports

Angular velocity is a useful concept in sports. For example, knowing and being able to control athwart as well every bit the linear velocity of a golf social club, a bat, or a racket during the swing may help the athlete with improving their functioning. A relationship between angular and linear velocity is such that for an elongated object such as a golf society the point furthest from the rotational axis has the fastest linear velocity, even though the athwart velocity is the aforementioned at whatever point along the club. Thus, using a longer club, bat, or racket the athlete can propel the brawl with a greater linear velocity, assuasive information technology to travel a longer altitude earlier it falls. Conversely, using a shorter noise or holding it up the grip in a style that shortens information technology allows the athlete to reduce the linear velocity.

Athletes with longer limbs can generate greater linear velocity

Taller people who accept longer limbs take an advantage when information technology comes to linear speed. This advantage may be one of the reasons why men were the primary hunters in primitive hunting, and too why humans evolved to exist taller considering hunting involves throwing stones and spears at the prey, and people with longer limbs can generate greater linear velocity. This could also exist a disadvantage, however. Not only does it require additional energy to throw objects for people with longer arms, but it would also injure more when people with longer legs hit an obstacle with their human foot, compared to shorter people, who move their legs at the same angular velocity. This is because the linear velocity of the human foot on the longer leg would be faster.

Angular velocity is important in gymnastics, figure skating, and diving. Knowing the average angular velocity allows the athletes to calculate how many acrobatic feats they tin complete earlier landing or entering the h2o. To perform more rotations like somersaults, athletes bring their legs and arms as shut equally possible to their body to minimize inertia and maximize momentum, which results in the increase in angular velocity. In lodge to land or to enter the water at a correct bending, the athletes may have to reduce their angular velocity by slightly extending the limbs, to gain more control of their movements.

Hammer and discus throwers also demand to generate high athwart velocities to exist able to increase the linear velocity. Just throwing the hammer without spinning it on a long cord generates much smaller velocity than if spinning it showtime. Many Olympic athletes spin the hammer three to four times before releasing it, to achieve the maximum possible linear velocity.

Angular Velocity in Optical Storage

The disks in hard disk drives are spun at speeds varying from 4,200 rpm in energy-efficient portable devices, to 15,000 rpm for high-performance servers

Angular velocity is used in data storage on optical media such every bit CDs. Both angular and linear velocities are used to mensurate the writing speed of discs and the speed of the disc drives. Different velocity is important in different recording modes, and the names of these modes often refer to velocity. For example, Constant Linear Velocity (CVL) method was the original recording mode. In this mode, information is written at a uniform rate through the entire disc. Zone Constant Linear Velocity (ZCLV) maintains a constant linear velocity in a given zone of the disc, non throughout the entire disc. The disc usually spins slower while recording on its outer areas. Partial Abiding Angular Velocity (PCAV) is a recording method of gradually increasing the angular velocity until a sure threshold is reached. It then remains abiding for the residuum of the recording. Finally, Constant Athwart Velocity (CAV) is a recording manner that maintains the angular velocity abiding during the recording. This means that the linear velocity increases every bit the writing head moves to the outer areas of the disc. This method is also used in hard drives and gramophone records.

Athwart Velocity in Space

Geostationary orbit

There is an orbit located 35,786 kilometers (22,236 miles) away from the Globe; an object post-obit this orbit in the aforementioned management as the rotation of the Earth completes it in approximately the aforementioned amount of time that it takes the Earth to rotate about its axis — one sidereal day, which is a little bit less than 24 hours. Thus, the athwart velocity of the objects on this orbit is equal to the athwart velocity of the World. Because of that, these objects await stationary to a viewer on Earth. This orbit is called a geostationary orbit.

It is used for satellites that monitor changes in the Globe's weather and climate (weather satellites), changes in the oceans (Geostationary Ocean Color Imagers or GOCIs), and communication satellites, used for dissemination and communication. Communication satellites can stay on lower or higher orbits besides. Geostationary orbits are oft used because the antennas pointed at a satellite on this orbit would not have to exist re-pointed. Withal, if the transmitter'south straight line of sight is blocked, the signal volition not be transmitted well, if at all. Geostationary orbit is far, and every bit a issue, information technology causes a delay of near 0.25 seconds. Stronger transmitters are needed to accost the issue of distance equally well. Historically advice satellites were used for long-distance telephone communications. They have been replaced in big part by marine cross-continental cables laid over the ocean floor, but are nonetheless used in this capacity for remote areas. In the past 20 years, communication satellites have as well been used to provide internet connectivity in remote locations.

Satellite dishes

Satellites accept a set amount of fuel, and once they use all of it, they cannot exist used anymore. They are generally taken to a different orbit, called a disposal or a graveyard orbit, which is much higher than the geostationary 1. Because of this most countries have regulations that require private satellite owners to sign an agreement that they will motility the satellite to the disposal orbit once it is near the end of its life cycle.

Angular Velocity and Rotational Frequency Converter

In physics, the angular velocity is defined as the charge per unit of alter of angular displacement and is a vector quantity that specifies the angular speed (rotational speed) of an object and the centrality well-nigh which the object is rotating.

The SI unit of athwart velocity is radians per second. It may exist measured in other units such as degrees per second, degrees per hr, etc. The management of the angular velocity vector is perpendicular to the plane of rotation, in a management which is usually specified by the right-hand rule. In engineering, older units such as revolutions per infinitesimal or revolutions per second are frequently used.

Notation: Integers (numbers without a decimal period or exponent notation) are considered accurate up to 15 digits and the maximum number of digits after the decimal betoken is 10.

In this reckoner, E notation is used to correspond numbers that are besides small or too big. E notation is an alternative format of the scientific note a · ten^x.
