How is momentum defined in relation to force?

• A. Momentum is constant when no net force acts.
• B. Momentum is equal to mass times velocity.
• C. Momentum decreases in the presence of external force.
• D. Momentum and force are directly proportional.

Answer: (B)

Momentum is defined as the product of an object's mass and its velocity, which means it can be quantified by the equation \( p = mv \). Here, \( p \) represents momentum, \( m \) is mass, and \( v \) is velocity. This definition highlights that an object's momentum depends both on how much mass it has and how fast it is moving. In a broader context, this understanding allows us to analyze the behavior of moving objects, particularly when exploring topics like collisions, changes in motion, and the conservation of momentum in isolated systems. While momentum can change due to external forces acting on an object, the fundamental definition based on mass and velocity remains consistent across all scenarios.
