Momentum is a
A
scalar Quantity
B
Vector Quantity
C
Always Constant
D
of thesenone
Explanation: 

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. See Newton’s laws of motion.

Detailed explanation-2: -Hence, momentum is a vector quantity.

Detailed explanation-3: -Momentum has magnitude and direction and obeys vector law of addition. Hence, it is a vector.

Detailed explanation-4: -Momentum is a vector quantity because it has magnitude as well as direction.

Detailed explanation-5: -Momentum is a vector quantity: it has both magnitude and direction. Since momentum has a direction, it can be used to predict the resulting direction and speed of motion of objects after they collide.
