An object's momentum is in the same direction as its velocity.

Here's why:

* Momentum is a measure of an object's mass in motion. It's calculated as: momentum = mass × velocity

* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.

* Since momentum is directly proportional to velocity, the direction of the momentum will always be the same as the direction of the velocity.
