Objects with the same velocity DO NOT necessarily have the same momentum.

Here's why:

* Momentum depends on both velocity AND mass.

* Momentum is calculated by: Momentum (p) = mass (m) x velocity (v)

* Two objects can have the same velocity but different masses.

* A small, fast-moving object can have the same velocity as a large, slower-moving object, but their momenta will be different.

Example:

* A tiny bullet traveling at 100 m/s will have a much lower momentum than a large truck traveling at the same 100 m/s.

To have the same momentum, two objects with the same velocity would need to have the same mass.
