Momentum is indeed considered a vector quantity, and this relates directly to its dependence on velocity. Momentum is defined mathematically as the product of an object's mass and its velocity. Since velocity is a vector quantity (having both magnitude and direction), momentum inherits this characteristic.

This means that when we calculate momentum, we must also account for the direction in which the object is moving. For example, if two objects have the same mass and speed but are moving in different directions, their momentum values will be different because the direction component of velocity affects the overall momentum vector.

The concept of momentum being a vector helps in understanding various physical scenarios such as collisions and conservation laws in physics, where the direction of momentum plays a crucial role in analyzing the outcomes. Thus, the correct understanding aligns with the premise that momentum relies on velocity, making it a vector quantity.
