Here's why:
* Momentum (p) is directly proportional to velocity (v):
p = mv (where m is mass)
* Decreasing momentum means either mass or velocity (or both) is decreasing.
Therefore, if momentum decreases, velocity MUST also decrease, unless the mass is increasing.
Example: Imagine a car slowing down. Its momentum decreases because its velocity decreases.
Conclusion: Velocity and momentum are directly related. Decreasing momentum implies a decrease in velocity, unless the mass is increasing.
