Final answer:
The angular momentum of an object depends on its mass and velocity (option a) , specifically the rotational motion characterized by moment of inertia and angular velocity.
Step-by-step explanation:
The angular momentum of an object depends on its mass and velocity. Specifically, angular momentum is a vector quantity that represents the product of an object's moment of inertia and its angular velocity. The moment of inertia itself is dependent on the object's mass and the distribution of that mass relative to the axis of rotation. Angular velocity is the rotational analog of linear velocity, and it measures how fast an object is rotating.
From the choices provided, option a) Mass and velocity is the correct answer. This is because the linear momentum of an object is proportional to its mass and velocity, and similarly, angular momentum is associated with mass and angular velocity, a rotational counterpart to linear velocity.
It's important to note that although linear motion can be described by mass and velocity alone, when dealing with rotational motion, the distribution of mass (moment of inertia) and the angular velocity are crucial for determining angular momentum.
