Angular displacement — of a body is the angle in radians (degrees, revolutions) through which a point or line has been rotated in a specified sense about a specified axis.When an object rotates about its axis, the motion cannot simply be analyzed as a particle, since… … Wikipedia
angular momentum — Physics. the product of the moment of inertia of a body about an axis and its angular velocity with respect to the same axis. Also called moment of momentum. [1865 70] * * * Property that describes the rotary inertia of a system in motion about… … Universalium
Displacement (vector) — Displacement versus distance traveled along a path. A displacement is the shortest distance from the initial to the final position of a point P[1]. Thus, it is the length of an imaginary straight path, typically distinct from the path actually… … Wikipedia
Poinsot's ellipsoid — In classical mechanics, Poinsot s construction is a geometrical method for visualizing the torque free motion of a rotating rigid body, that is, the motion of a rigid body on which no external forces are acting. This motion has four constants:… … Wikipedia

Precession — For other uses, see Precession (disambiguation). Precession of a gyroscope Precession is a change in the orientation of the rotation axis of a rotating body. It can be defined as a change in direction of the rotation axis in which the second… … Wikipedia
Rotation around a fixed axis — Rotational motion can occur around more than one axis at once, and can involve phenomena such as wobbling and precession. Rotation around a fixed axis is a special case of rotational motion, which does not involve those phenomena. The kinematics… … Wikipedia

Screw axis — The screw axis (helical axis or twist axis) of an object is a parameter for describing simultaneous rotation and translation components of that object.The axis is a directed line in space, along which a translation may occur, and about which… … Wikipedia
mechanics — /meuh kan iks/, n. 1. (used with a sing. v.) the branch of physics that deals with the action of forces on bodies and with motion, comprised of kinetics, statics, and kinematics. 2. (used with a sing. v.) the theoretical and practical application … Universalium
