Final answer:
Angular momentum depends on three factors: mass, velocity, and radius, and it is a conserved vector quantity that determines the rotational motion of an object.
Step-by-step explanation:
Angular momentum is a critical concept in physics that defines the rotational motion of an object around a fixed point. The three factors that influence the angular momentum of an object are its mass, the velocity at which it moves, and the radius of its path around the central point (the point it is orbiting around).
To visualize the direction of angular momentum, the right-hand rule is used, which shows that angular momentum is directed perpendicular to the plane of rotation and points along the axis of rotation. Angular momentum is also a conserved quantity, meaning it remains constant unless acted upon by an external torque.
