This page provides all possible meanings and translations of the word velocity
distance travelled per unit time
A vector quantity that denotes the rate of change of position with respect to time, or a speed with the directional component.
Rapidity of motion.
The rate of occurrence.
The number of times that an average unit of currency is spent during a specific period of time.
Origin: From velocitas, from velox.
quickness of motion; swiftness; speed; celerity; rapidity; as, the velocity of wind; the velocity of a planet or comet in its orbit or course; the velocity of a cannon ball; the velocity of light
rate of motion; the relation of motion to time, measured by the number of units of space passed over by a moving body or point in a unit of time, usually the number of feet passed over in a second. See the Note under Speed
In kinematics, velocity is the rate of change of the position of an object, equivalent to a specification of its speed and direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving. If a car is said to travel at 60 km/h, its speed has been specified. However, if the car is said to move at 60 km/h to the north, its velocity has now been specified. To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path. Thus, a constant velocity means motion in a straight line at a constant speed. If there is a change in speed, direction, or both, then the object is said to have a changing velocity and is undergoing an acceleration. For example, a car moving at a constant 20 kilometres per hour in a circular path has a constant speed, but does not have a constant velocity because its direction changes. Hence, the car is considered to be undergoing an acceleration. Velocity is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value of velocity is called "speed", a quantity that is measured in metres per second when using the SI system. For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector. The rate of change of velocity as a function of time is "acceleration", which describes how an object's speed and direction of travel change at each point in time. In science a "deceleration" is called a "negative acceleration", for example: −2 m/s².
The Standard Electrical Dictionary
The rate of motion of a body. It is usually expressed in distance traversed per second of time. The absolute unit is one centimeter per second or kine. The foot per second is very largely used also. The dimensions of velocity are length (L) divided by time (T) or L/T.

No one expected this, this kind of understanding of the connection between velocity, time and distance was thought to have emerged only around 1350 AD.
They are ejected from the rocket in different directions at high velocity, essentially acting as space buoys, to create a network of measurements that will allow us to see the structure of the aurora over a much wider area than was possible before.
Far and away, the most important takeaway from the The Fed meeting is their expectations of the velocity of the rate rise, i know that they don't have a crystal ball, but I want to get a better expectation for how quickly they expect to raise rates.

The alignment on the stairs, the leveling of the wheelchair driver, is automated and he can control it, he can view the back with a back facing camera, and have a full, safe, driving experience.
