In introductory physics, an object’s linear momentum is given by $p=mv$. Which two factors determine the magnitude of an object’s momentum?

• A. Its mass and its velocity
• B. Its kinetic energy and its mass
• C. Its velocity and the net force acting on it
• D. Its mass and its acceleration

Answer: (A)

Verified step by step guidance

1. Recall the definition of linear momentum in physics, which is given by the formula \(p = m \times v\), where \(p\) is momentum, \(m\) is mass, and \(v\) is velocity.
2. Identify the variables in the formula: momentum depends directly on the mass of the object and its velocity.
3. Understand that kinetic energy, net force, and acceleration are related concepts but are not the direct factors determining momentum.
4. Recognize that since momentum is the product of mass and velocity, these two quantities determine the magnitude of momentum.
5. Conclude that the correct factors determining the magnitude of an object's momentum are its mass and its velocity.
