During purely translational motion (motion with no rotation), all points on a rigid body move with the same velocity.

By selecting the center of gravity as the reference point for a rigid body, the gravity forces will not cause the body to rotate, which means weight of the body can be considered to be concentrated at the center of mass.

In perfect two body motion, these orbital elements would be invariant (just like the Keplerian elements would be).

In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it.

Six degrees of freedom The motion of a ship at sea has the six degrees of freedom of a rigid body, and is described as Translation Moving up and down (heaving) Moving left and right (swaying) Moving forward and backward (surging) Rotation Tilts forward and backward (pitching) Swivels left and right (yawing) Pivots side to side (rolling).

However, when motion involves rotation, the instantaneous velocity of any two points on the body will generally not be the same.

The two body problem can be re formulated as two one body problems, a trivial one and one that involves solving for the motion of one particle in an external potential.

In a rigid body vortex flow of a fluid with constant density, the dynamic pressure is proportional to the square of the distance r from the axis.

A rigid body is called chiral if its mirror image is different in that sense, i.e., if it has either no symmetry or its symmetry group contains only proper rotations.

An environmental psychologist told me, If you're sitting in a hard chair on a rigid surface, you'll be more rigid.

Seals, in contrast, undulate their bodies to move on land, similar to the up and down body motion used underwater by many aquatic mammals (dolphins, manatees).

Motion Blur

In Jordan, the Hijab means covering the entire body with a robe which covers the neck and a scarf which goes in a circular motion around the head.

That is to say, it excludes any kinetic or potential energy the body may have because of its motion or location in external gravitational, electrostatic, or electomagnetic fields.

You mix them together and they make a rigid double helix.

Second, China s financial system is fragile, and its economic structure rigid.

One motion has been denied, one motion has been withdrawn by the Prosecution, and the Prosecution has indicated that it will soon withdraw another motion (Rajić guilty plea).

Rigid timetables that history suggests would not be met should be eschewed.

I note however that, as stated previously, one motion has been denied, one motion was withdrawn by the Prosecution, and the Prosecution has indicated it will soon withdraw another 11bis motion.

In addition to the proposer of the motion, one member may speak in favour of and one against the motion, after which the motion shall immediately be put to the vote.

In addition to the person who proposed the motion, one member may speak in favour and one against the motion, after which the motion shall immediately be put to the vote.

And that means that China also must reconsider its rigid notion of sovereignty.

Rigid rules and distant policymakers merely suffocate the animal spirits of the business class.

g This section provides that The applicant may request a review of the lawfulness of dealing with his motion by filing a repeated motion this new motion shall be dealt with by a superior prosecutor.

One motion involving three accused was withdrawn by the prosecution, while another motion involving one accused was denied by the Chambers.

So who put this machinery in motion?

Permission to speak on a motion to reconsider shall be accorded only to two speakers in favour of the motion and two speakers opposing the motion, after which it shall immediately be put to the vote.

More importantly, even the regulators themselves have ceased to believe in obsolete and rigid doctrines.

Permission to speak on a motion to reconsider shall be accorded only to two speakers in favour of the motion and to two speakers opposing the motion, after which it shall be immediately put to the vote.

It's kind of like skydiving in slow motion.
