alleryMomentum p of a body of mass m moving with velocity v is defined as:
Ap = m v
Bp = ½ m v²
Cp = m / v
Dp = m v²
Answer & Solution
Correct answer: A. p = m v
1. Momentum is a vector quantity equal to the product of mass and velocity.
2. p = m v, with direction the same as v.
3. Kinetic energy ½mv² is a scalar and not momentum.
