Answer : The correct option is, The product of mass and velocity.
Explanation :
Momentum : It is defined as the motion of a moving body. Or it is defined as the product of mass and velocity of an object.
Formula of momentum is:
![p=mv](https://img.qammunity.org/2020/formulas/physics/middle-school/lldmrpmkc3i68kifbfb2c4hi3vblitcsch.png)
where,
p = momentum
m = mass of object
v = velocity of object
Hence, correct option is, The product of mass and velocity.
