Angular frequency is a scalar quantity that represents the rate of change of an oscillating object with respect to time. It is measured in radians per second and is a scalar because it only has a magnitude and no direction associated with it.
Yes, angular momentum is a vector quantity. It has both magnitude and direction, with the direction given by the right-hand rule for rotating systems.
Yes, angular displacement is a vector quantity because it has both magnitude and direction. The direction of angular displacement is determined by the axis of rotation.
Solid angle is a scalar quantity, not a vector. It measures the angular extent or size of a region in three-dimensional space and does not have a specific direction associated with it.
Angular acceleration is a vector quantity because it has both magnitude (rate of change of angular velocity) and direction in rotational motion. The direction of angular acceleration aligns with the axis of rotation it is acting upon.
Angular velocity is a vector quantity that describes the rate of rotation of an object about an axis. It has both magnitude (how fast the object is rotating) and direction (the axis of rotation). Scalar angular velocity only considers the magnitude of the rotation rate without specifying the direction.
