Answer 2

The physical significance of momentum is a vector quantity of motion of an object, as well as force is a vector quantity of an action exerted by external body, etc. Momentum shows us how much motion the moving body has and where it is directed, and very important thing it makes it possible to measure the distribution of the momentum when a moving object collides with another object. Using momentum you can compare two moving objects, if their momentums are equal you can feel the same impact when they bump into you, in the language of formulas it means that the product mass * velocity is the same for them. There are two other physical quantities characterizing the motion of an object: first one - velocity, the difference from momentum is that it does not take into account the mass of an object, two objects with different masses can possess the same velocity, but you have to agree that the impact of a ball moving at 10 m/s is much softer than that of a truck with the same speed. The second one is kinetic energy which does not shows us in what direction the motion occurs i.e. it is a scalar quantity.
Finally we conclude that, momentum is a vector quantity telling us about some important characteristics of an object, measurable only during motion: its mass*speed quantity (impact) and direction of motion.
\[\bar p = m \bar v\]
The bar sign above the letters in the formula mean that they represent vectors, quantities having direction besides their numerical value.
p - linear momentum of a point mass, having mass m, and velocity v.
