Momentum is calculated by multiplying which quantities?

• A. Force times distance
• B. Mass divided by velocity
• C. Mass times velocity
• D. Velocity times acceleration

Answer: (C)

Momentum is the quantity of motion an object has, calculated as mass times velocity. This directly ties how much matter there is to how fast it’s moving, so heavier objects and faster objects carry more momentum. In many situations, especially in skiing dynamics, momentum is conserved when no external forces act, which is why p = m v is a fundamental relation in analyzing collisions and turns. The other pairings don’t describe momentum. Force times distance is work, not momentum. Mass divided by velocity isn’t a standard physical quantity for motion. Velocity times acceleration isn’t momentum either; it’s related to how quickly the kinetic energy is changing, not the current motion carried by the object.
