rectilinear motion

"That God could not move the heavens with rectilinear motion; and the reason is that a vacuum would remain."

Rectilinear motion: Ideal terrestrial motion would proceed straight up or straight down at constant speed.

There are two types of translatory motions: rectilinear motion; curvilinear motion.

At the other was a connecting-rod which, in changing the rectilinear motion to a circular one, was directly connected with the shaft of the paddles.

The angular momentum of a particle or rigid body in rectilinear motion (pure translation) is a vector with constant magnitude and direction.

Because objects radiate light in rectilinear motion in all directions, the eye must also be hit with this light at all points.

Linear motion (also called rectilinear motion) is motion along a straight line, and can therefore be described mathematically using only one spatial dimension.

Rectilinear motion (Linear motion) - motion which follows a straight linear path, and whose displacement is exactly the same as its trajectory.

But the two forms of rectilinear motion are opposed to one another by reason of their places; for up and down is a difference and a contrary opposition in place.

All inertial frames are in a state of constant, rectilinear motion with respect to one another; an accelerometer moving with any of them would detect zero acceleration.

Lichtenberg originally believed (like Descartes) that every explanation of natural phenomena must be based on rectilinear motion and impulsion, and Le Sage's theory fulfilled these conditions.

Preston Samuel Tolver Preston illustrated that many of the postulates introduced by Le Sage concerning the gravitational particles, such as rectilinear motion, rare interactions, etc..

Again, the primary substance has rectilinear motion in two directions, backwards and forwards, at once a condensation, which produces cohesion and substance, and an expansion, the cause of extension and qualities.

Maybe they move about like snakes, he thought, picturing the alternate lifting and dropping of scales that the limbless reptiles employed in rectilinear motion, giving the impression of sliding along smoothly in a straight line.

Inertia replaced the medieval impetus theory, that unnatural motion ("forced" or "violent" rectilinear motion) is caused by continuous action of the original force imparted by a mover into that which is moved.

In the general case of rectilinear motion, when the net force F is not constant in magnitude, but is constant in direction, and parallel to the velocity of the particle, the work must be integrated along the path of the particle:

Secondly, it may be thought that the same reasoning which holds good of the rectilinear path applies also the circular, movement from A to B being opposed as contrary to movement from B to A. But what is meant is still rectilinear motion.

According to Duhem, "if we must assign a date for the birth of modern science, we would, without doubt, choose the year 1277 when the bishop of Paris solemnly proclaimed that several worlds could exist, and that the whole of heavens could, without contradiction, be moved with a rectilinear motion."

An arbitrarily shaped rigid rotor is a rigid body of arbitrary shape with its center of mass fixed (or in uniform rectilinear motion) in field-free space R, so that its energy consists only of rotational kinetic energy (and possibly constant translational energy that can be ignored).

Treatise on the Rectilinear Motion and Rotation of Bodies (Cambridge, 1784), which gives some interesting experiments, by means of which mechanical truths can be ocularly exhibited and demonstrated, and describes the machine, since named after Atwood, for verifying experimentally the laws of simple acceleration of motion.
