Answer:
Angular momentum and angular velocity have both magnitude and direction and, therefore, are vector quantities.
Explanation:
The vectors point along the axis of rotation with a direction determined by an arrow.
What is a vector?
There are two types of physical quantity one is a scaler and another one is a vector.
The quantity that requires only megnitude to define is known as the scalar quantity. While the vector quantities need both megnitude and the direction to define.
The vector quantity is represented by an arrow. The vectors point along the axis of rotation with a direction determined by an arrow.
The angular quantities L, omega, and alpha are vector quantities.
Hence arrow is the correct answer for the blank.
