Which statement about momentum is true according to the material?

• A. False
• B. True
• C. Not mentioned
• D. Not sure

Answer: (B)

Momentum is defined as p = m v, a vector quantity that combines an object's mass, speed, and direction. A statement about momentum is true when it aligns with this definition and the standard laws, such as momentum being conserved in a closed system (no external net impulse) and impulse equaling the change in momentum (Δp = ∫ F dt). If the material states one of these accurate facts, that statement is true. This is why the correct choice reflects truth about how momentum behaves in real situations. The other options would misrepresent the standard facts, whereas the material’s true statement matches the established understanding of momentum.
