When a vessel is brought to a stop, what happens to its momentum?

• A. it decreases instantly
• B. it continues at the same speed
• C. it increases
• D. it reduces gradually

Answer: (D)

When a vessel is brought to a stop, its momentum reduces gradually. Momentum is the product of an object's mass and its velocity. When a vessel is moving and then begins to decelerate or stop, the effects of friction, water resistance, and propulsion systems contribute to a decrease in velocity over time. This gradual reduction allows for a smoother stop and helps ensure safety for passengers and the vessel itself. If the momentum were to decrease instantly, it could lead to abrupt shifts or jarring motions that could be dangerous onboard. Thus, the gradual reduction in momentum reflects the physical forces acting on the vessel and aids in maintaining stability and safety during the stopping process.
