* Momentum: Momentum is a measure of an object's mass in motion. It's calculated as:
* Momentum (p) = mass (m) * velocity (v)
* Constant Velocity: If the velocity of an object remains the same (both in speed and direction), then the velocity term (v) in the momentum equation stays constant.
* No Change in Momentum: Since mass is usually constant for an object, and velocity isn't changing, the product of mass and velocity (momentum) also remains constant. This means there is no change in momentum.
Important Note: This applies when the object is moving in a straight line. If the object changes direction (even if its speed stays the same), its velocity changes, and therefore its momentum changes.
