Which of the following is not a factor in calculating $p$ (momentum)?

• A. Direction of motion
• B. Acceleration of the object
• C. Velocity of the object ($v$)
• D. Mass of the object ($m$)

Answer: (B)

Verified step by step guidance

1. Recall the formula for momentum, which is given by \(p = m \times v\), where \(p\) is momentum, \(m\) is the mass of the object, and \(v\) is the velocity of the object.
2. Understand that velocity \(v\) is a vector quantity, meaning it has both magnitude and direction. Therefore, the direction of motion directly affects the momentum since momentum is also a vector.
3. Note that acceleration is the rate of change of velocity with respect to time, but it is not directly used in the calculation of momentum at a given instant.
4. Identify that the factors involved in calculating momentum are mass \(m\) and velocity \(v\) (including its direction), but not acceleration.
5. Conclude that among the options given, acceleration of the object is not a factor in calculating momentum.
