# A report onRotation around a fixed axis and Angular velocity        Orbital angular velocity refers to how fast a point object revolves about a fixed origin, i.e. the time rate of change of its angular position relative to the origin.

- Angular velocity

The angular velocity vector also points along the axis of rotation in the same way as the angular displacements it causes.

- Rotation around a fixed axis ## 3 related topics with Alpha ## Rotation       Rotation is the circular movement of an object around an axis of rotation in either the clockwise or counterclockwise direction.

The angular velocity vector (an axial vector) also describes the direction of the axis of rotation. ## Right-hand rule

Common mnemonic for understanding orientation of axes in three-dimensional space.

Common mnemonic for understanding orientation of axes in three-dimensional space.       In mathematics, a rotating body is commonly represented by a pseudovector along the axis of rotation.

The length of the vector gives the speed of rotation and the direction of the axis gives the direction of rotation according to the right-hand rule: right fingers curled in the direction of rotation and the right thumb pointing in the positive direction of the axis. ## Rigid body
