In dynamics, the spin (rotational speed) of a rigid body.
Also called rotational velocity, it is the amount of rotation that a spacecraft undergoes per unit time. For Landsat 7 it is equal to 1.059 mrad/sec ((233 paths/cycle * 2*pi*1000 mrad/path) / (16 days/cycle * 86400 sec/day)).
The rate of rotation of a particle about the axis of rotation, with magnitude equal to the time rate of angular displacement of any point of the body. Angular velocity is a vector oriented in accordance with a right-hand rotation (i.e., when the fingers of the right hand are curved in the sense of rotation, the thumb points in the direction of the angular velocity vector).
the rate of change of angular displacement in time.
The rate at which a body rotates as expressed by an angular change of position per unit time.
The rate of speed at which a component is rotating.
The time rate of change of angular displacement.
The rate of change of angular position of a rotating body.
The velocity of an object due to the angle at which it lies, as compared to a larger source of gravity.
the rate at which a spinning body rotates.
A vector quantity, , that reflects the change of angular displacement with time, and is typically given in units of rad/s. To find the direction of the angular velocity vector, take your right hand and curl your fingers along the particle or bodyâ€(tm)s direction of rotation. Your thumb then points in the direction of the bodyâ€(tm)s angular velocity.
In physics, the angular velocity is a vector quantity (more precisely, a pseudovector) which specifies the angular speed at which an object is rotating along with the direction in which it is rotating. The SI unit of angular velocity is radians per second, although it may be measured in other units such as degrees per second, degrees per hour, etc. When measured in cycles or rotations per unit time (e.g. revolutions per minute), it is often called the rotational velocity and its magnitude the rotational speed.
