Detailed explanation-1: -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.
Detailed explanation-2: -From this point, we can conclude momentum is a vector quantity. Momentum is a vector quantity because it has magnitude as well as direction. E.g. we say the momentum of a object is 5 kg⋅m/s 5 k g ⋅ m / s along the east.
Detailed explanation-3: -Momentum is the product of mass and velocity of a body. Mass is a scalar, and velocity is a vector. A vector multiplied by a scalar quantity results in a vector. So, momentum is a vector quantity, and its direction depends on that of the object’s velocity.
