Physicists interpret this as the object experiencing a force in the opposite direction of its initial motion. Consider a scenario where a ball moving rightward with positive momentum strikes a wall and rebounds leftward.
Understanding the Baseball Catcher's Negative Momentum Shift
A baseball player catching a fastball pulls their hand back to increase the time over which the ball's momentum changes. Its final momentum is negative relative to the initial state.
Momentum, defined as the product of mass and velocity, is a vector quantity, meaning it possesses both magnitude and direction. The Physical Interpretation of Negative Change A negative change in momentum does not imply a disappearance of motion, but rather a reversal or opposition to the initial direction of travel.

Conclusion on Vector Nature Ultimately, the answer to whether change in momentum can be negative is a definitive yes, and it is a direct consequence of the vector nature of the quantity. When analyzing motion, the question of whether a change in momentum can be negative is fundamental to understanding the behavior of objects under force.
