The moving object's momentum depends on its mass and velocity.

Here's why:

* Momentum is a measure of how much motion an object has. It's a fundamental concept in physics.

* Mass is the amount of matter in an object. A more massive object has more inertia (resistance to change in motion).

* Velocity is the object's speed and direction.

The formula for momentum is:

Momentum (p) = Mass (m) x Velocity (v)

This means:

* A heavier object (more mass) moving at the same speed as a lighter object will have more momentum.

* An object moving faster will have more momentum than the same object moving slower.
