Sentences with phrase «which rotational motion»

This rules out reciprocal motion — such as the way a fish uses their fins — so the microswimmers must rely on nonreciprocal motion similar to that of bacterial flagella, in which rotational motion is converted to translational motion.

Not exact matches

Rotational or circular motion gives rise to, for example, the familiar centrifugal force, the presence of which may be recognized without reference to changes in motion relative to any surrounding system of material objects.8 Newton illustrates the significance of this step in his position with his famous «bucket experiment» (PNP 10f).9

In physics, torque can informally be thought of as «rotational force» or «angular force» which causes a change in rotational motion.

«Very short laser pulses, which last only a few billionths of a second, are shot at different positions in space to determine the speed, direction of motion and the rotational motion of the objects,» explains Dr. Dr. Oliver de Vries.

The scientists also found powerful, large sloshing motions, which temporarily switch over to rapid, strong rotational motions.

The chemists then studied the intermediate using microwave spectroscopy, which revealed details of its rotational motions.

Each stroke leads to greater range of motion around the shoulder joint and through the torso and hips, which is particular helpful for sports that demand rotational motion like baseball, golf, or even the throwing motion in football.

Here's the problem: Since the weight never travels up or down and remains in the same horizontal plane of motion, the rotator cuff — which is supposedly responsible for directing rotational movements at the shoulder — never gets activated.

At face value it requires that no energy can be transfered via collisions, i.e. no thermal conductivity, no viscosity, no diffusion... Even for CO2, there is no mechanism for the transfer of energy from rotational / vibrational degrees of freedom to translational motion which has no coupling with a radiation field.
