Momentum is the product of an object's speed and ___.

Explanation:
Momentum is found by multiplying how much matter is in an object (mass) by how fast it is moving (speed or velocity). Mass is an intrinsic property that doesn’t depend on gravity, so it reliably scales with motion. Weight depends on gravity and can change with location, while volume and density don’t directly determine how much motion an object has. So the factor that pairs with speed to give momentum is mass. For example, keeping speed the same, doubling the mass doubles the momentum; changing volume or density doesn’t produce that direct, consistent effect.
