In physics, the angular velocity is defined as the rate of change of angular displacement and is a vector quantity (more precisely, a pseudovector) which specifies the angular speed (rotational speed) of an object and the axis about which the object is rotating.

Vector fields A vector field is an assignment of a vector to each point in a subset of space.

The target DNA sequence is then inserted into a cloning vector.

Vector Arena is an indoor arena.

Bulletin of the Society for Vector Ecology 13 60 81.

The numerical output, however, might also be a vector or a shape.

At the point a , these partial derivatives define the vector formula_17This vector is called the gradient of f at a .

The vehicle, called the ThrustSSC ( Super Sonic Car ), captured the record 50 years and one day after Yeager's first supersonic flight.

So the idea was, okay, keep that feeling of freedom, but change the vector and increase the time.

Scalable Vector Graphics (SVG) is an XML based vector image format for two dimensional graphics with support for interactivity and animation.

However, the speed of sound varies from substance to substance.

formula_19where formula_20 is the transverse velocity formula_21 is the radial velocity.

Narrator Do you have a need for speed?

In fluid dynamics, Mach number (M or Ma) ( ) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound.

the average speed as it completes an orbit, or the speed at a particular point in its orbit.

In the Southern Hemisphere, the water is transported to the left of the wind.

There's no speed limit.

Respect the speed limits!

Respect the speed limits!

The type of explosives used in mining are high explosives which vary in composition and performance properties.

The exchange of virtual pions, along with the vector, rho and omega mesons, provides an explanation for the residual strong force between nucleons.

Don't exceed the speed limit.

Critical ionization velocity The critical ionization velocity is the relative velocity between an ionized plasma and a neutral gas, above which a runaway ionization process takes place.

Speed and death.

Globalisation is the speed of light.

Operations Network System characteristics The trains are supplied by 3000 V DC overhead wires, and have a commercial speed of 40 km h with a maximum speed of 80 km h.

Velocity and speed The velocity of a particle is a vector that tells about the direction and magnitude of the rate of change of the position vector, that is, how the position of a point changes with each instant of time.

Even though angular velocity, angular frequency and the unit hertz all have the dimension 1 s (reciprocal second), angular velocity and angular frequency are not expressed in hertz, but rather in an appropriate angular unit such as radians per second.

In particular, the speed of light in a medium is less than in vacuum, which means that the same frequency will correspond to a shorter wavelength in the medium than in vacuum, as shown in the figure at right.

Average velocity can be calculated as formula_1The average velocity is always less than or equal to the average speed of an object.

This is a high speed centrifuge.

Here we have it running at high speed mode.

Watch out! There's a speed camera.

The motorcyclist exceeded the speed limit.

They have been observed to walk at a speed of .

The speed limits were temporarily lowered.

So this is slowed down.

So here is normal speed.

Speed isn't everything.

The decrease of the sound speed with height is referred to as a negative sound speed gradient.

Therefore, the speed of travel around the orbit is formula_57,where the angular rate of rotation is ω.

The complementary particle types are called luxon (always moving at the speed of light) and bradyon (always moving slower than light), which both exist.
