■ ADJECTIVE

angular

When considering circular motion it is often easier to work in terms of the angular velocity rather than ordinary linear velocity.

The Lift's wide, so the angular velocity is higher on the outside.

constant

The 109 V8 has constant velocity joints within its hubs.

Our model requires two sites of learning so that constant head velocity can generate constant eye velocity.

According to an experiment carried out in 1897, light always travels at the same constant velocity .

The mass column density along a line-of-sight for a constant outflow at velocity v is therefore.

Reciprocal motion Reciprocal motion, positive and negative at constant mean velocity , is unnerving, mechanistic and inhuman.

different

Notice that one frame in free fall can have a very different velocity and acceleration from another such frame.

How is it that observers moving with different uniform velocities can be equivalent with respect to Minkowskian geometry?

high

The true velocities may be higher than the velocities measured in projection.

There were early experiments, some of them successful, in which objects moving at high velocity were arrested by the camera.

The smaller the proportion, the lower the demand and obviously the higher is velocity .

He was in no hurry, and it was dangerous to move at a high velocity so near the ship.

Very high velocities have been observed in the movement of spray rising from impacts of this type.

This could be a direct consequence of the high internal velocity dispersion in the molecular clouds.

low

What ever the bone type, however, Dodson found that very low water velocities were sufficient to move small mammal bones.

Throughout the campaign troops have been issued with various flak jackets which give a degree of protection against low velocity rounds.

maximum

A maximum velocity at the equator reduces to a theoretical nil at the poles.

The maximum possible impact velocity for a solar system body striking Earth is a little more complicated to calculate.

The motor velocity increases under the influence of the positive torque and the equilibrium position is attained with maximum velocity.

Accelerating violence and horror eventually hit maximum velocity and warp into nonsense, no matter how erudite the script.

mean

The mean velocity also varies vertically, and we shall confine attention to two-dimensional flow.

Firstly, the mean velocity profile may be liable to local instability, somewhat analogous to instability of laminar flow.

The turbulence is being kept going by the working of this against the mean velocity gradient.

No differences in mean linear growth velocities were found between males and females or among patients stratified by anatomical localisation of disease.

Reciprocal motion Reciprocal motion, positive and negative at constant mean velocity , is unnerving, mechanistic and inhuman.

In most turbulent flows, for example, only the mean velocity can be measured with a Pitot tube.

relative

That way it might be easier to match relative velocities for a few seconds.

Their impact energy per gram increases with the square of their relative velocity .

When this Doppler shift is converted to relative velocity it turns out that the velocity varies sinusoidally with time.

■ NOUN

escape

As the star shrank, the gravitational field at the surface would become stronger and the escape velocity would increase.

Some of the gases from the explosion and fireball may reach escape velocity .

This critical speed is called the escape velocity .

A significant fraction of their water content can emerge from the explosion at a speed below the escape velocity of Mercury.

As the radius of the star is reduced the escape velocity increases until eventually it reaches the velocity of light.

In fact, it is traveling well above escape velocity .

Jupiter is a very massive planet, and its escape velocity is correspondingly high.

Even modest-sized impactors can blast atmospheric gases off of Mars at speeds above escape velocity .

fluctuations

The investigation of the flow past obstacles or of boundary layers requires a uniform flow with minimal velocity fluctuations .

At large r the velocity fluctuations become independent of one another and R asymptotically approaches 0.

Figure 21.4 shows oscillograms of the velocity fluctuations at different distances from the centre line of a wake.

Figure 24.9 shows vertical velocity fluctuations in a different Bénard experiment.

In principle, of course, correlations involving the pressure fluctuations as well as the velocity fluctuations may be formulated.

The flow outside the interface, although called non-turbulent, does involve velocity fluctuations .

This term represents the action of the velocity fluctuations on the mean flow arising from the non-linearity of the Navier-Stokes equation.

However, these velocity fluctuations are entirely irrotational and are dynamically quite different from turbulent fluctuations.

profile

The final technique for producing a velocity profile involves a voltage.controlled oscillator with the controlling voltage generated by an analogue circuit.

Firstly, the mean velocity profile may be liable to local instability, somewhat analogous to instability of laminar flow.

These changes arise from changes in the laminar velocity profile .

It is likely that these coherent structures originate through an intermittent instability of the velocity profile .

The look.up table entries can be calculated, using the methods described in Section 6.3 to determine the optimum velocity profile .

Figure 21.26 shows velocity profiles at two distances downstream from the start of the heated section.

Simultaneously, they interact with the mean flow, so that the velocity profile also has three-dimensional variations.

Derive the velocity profile for optimum acceleration of this system.

wave

Calculations of frequency and wave velocity of motility could be derived directly from the screen.

■ VERB

determine

In consequence the use of sedimentation columns or tubes to determine the fall velocities of sediment particles has become very popular.

The look.up table entries can be calculated, using the methods described in Section 6.3 to determine the optimum velocity profile.

give

Maintaining a given velocity round a curve requires acceleration towards the centre of curvature.

increase

A spacecraft at point A carries out a burn that increases its horizontal velocity .

In the Jupiter fly-by, the ship had used the gravitational field of the planet to increase her velocity .

This is exactly the case of NBFIs increasing velocity that we discussed above.

The subsequent path it takes will depend on whether the A V increased or decreased the velocity .

The wind had increased in velocity and was now a low, angry howl.

measure

The more precisely you measure the position of a particle, the less precisely you can measure its velocity , and viceversa.

move

There were early experiments, some of them successful, in which objects moving at high velocity were arrested by the camera.

He was in no hurry, and it was dangerous to move at a high velocity so near the ship.

How is it that observers moving with different uniform velocities can be equivalent with respect to Minkowskian geometry?

reach

As the radius of the star is reduced the escape velocity increases until eventually it reaches the velocity of light.

Some of the gases from the explosion and fireball may reach escape velocity .

As the sun shrinks it rotates faster, and flings off its outer, much cooler shell when it reaches escape velocity .
