Detailed explanation-1: -Momentum, p→=mv→ acts in the direction of applied velocity, a vector, hence momentum requires both magnitude & direction to be fully described making it a vector.
Detailed explanation-2: -momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. See Newton’s laws of motion.
Detailed explanation-3: -Momentum is a vector quantity because it has magnitude as well as direction.
Detailed explanation-4: -Velocity Vector Recall that velocity is a vector with both magnitude and direction.
Detailed explanation-5: -A vector has both magnitude and direction.
