radius vector

Joelle wondered why the radius vector was not longer, much longer.

Accelerate at about forty-five degrees to our present radius vector around that sun you see, inward.

At this moment the navigator reported: "13 kilometres radius vector, sir.

The radius vector describes equal areas in equal times.

The readout consisted of three triangular coördinates and a radius vector.

That "of course" refers to Kepler's Laws, the one about radius vectors and equal areas.

All traffic within radius vector of SOS has been halted.

The radius vector indicated the distance between the BOB 21 and the unknown transmitter.

The radius vector gave the distance of the object from the coordinate origin, that is Arkon, in parsecs.

The ship was placed in a temporary orbit half a billion miles from the Sun with a radius vector normal to the plane of the ecliptic.

Then the radius vectors from the axis to all particles undergo the same angular displacement in the same time.

For the LB-level the function simply runs through the possible gradients of the radius vector and selects the maximum.

Flame Disc held an orbit of twice the radius vector of Pluto-assuming that it existed.

Here Newton finds the centripetal force to produce motion in this configuration would be inversely proportional to the square of the radius vector.

For spherical coordinates, θ is the angle between the z axis and the radius vector connecting the origin to the point in question.

Hence a reasonable lower bound is the maximum gradient of the radius vector in the interval blackout point, whiteout point.

R-bar or Earth Radius Vector is an imaginary line connecting the space station to the center of the Earth.

Let ψ denote the angle between the tangent line and the radius vector, sometimes known as the polar tangential angle.

The center of mass of the ball is moving perpendicular to the radius vector (from pivot to center of mass).

The quantity omega () in this last equation is similar to the Coulomb potential, except that the radius vector is shifted by an imaginary amount.

It can be seen that the potential at a point specified by radius vector due to both charges alone is given by the sum of the potentials:

The transverse (or tangential) acceleration is directed at right angles to the radius vector and takes the sign of the angular acceleration ().

Recalling that the velocity and radius vectors are perpendicular at apoapsis and periapsis, conservation of angular momentum requires , thus :

The angle formed between the radius vector and the vertical axis was Theta, and that formed with the horizontal axis was Phi.

Additional science instruments could also be located in the Wheel, generally looking out on a rotating radius vector which scanned the sky, and also across the Sun, every few seconds.
