Momentum- Law of conservation of Momentum

The total momentum of the system is equal to each other. "The total momentum of an isolated system that is interacting will not change,"

"The total momentum of an isolated system before a collision is always the same as the total momentum after a collision."

Let's consider an independent system consisting of two objects "A" and "B" as shown. The quality of the body is ma and mb.

The above equation is a statement of momentum conservation law. At the time of a collision, the momentum change of the object 1 is the same as the momentum change of the object 2 and is opposite. That is, the momentum lost by the object 1 is equal to the momentum obtained by the object 2. For most collisions between two objects, one accelerates and the other loses momentum as the momentum increases. If object 1 loses 75 units of momentum, object 2 gains 75 units of momentum. However, the total momentum of the two objects (object 1 and object 2) is the same as before the collision. The total momentum of the system (a collection of two objects) is saved

The statement above indicates that the total momentum of the object set (system) is preserved. In other words, total momentum is constant or constant value. This momentum conservation law will be the focus of the rest of lesson 2. To understand the basics of momentum conservation, let's start with a short logical proof. Forces act between two objects for a while. In some cases the time is long, in other cases the time is short. Regardless of the length of time, the time the force acts on the object 1 can be said to be equal to the time the force acts on the object 2. This is logical. Forces interaction (or contact) between two objects. If object 1 is in contact with object 2 for 0.050 seconds, object 2 must be in contact with object 1 for the same time (0.050 seconds). As an equation, this can be expressed as:

The momentum conservation law shows that when two objects collide, the force lost by one object is equal to the force obtained by the other. The total momentum of the system after collision is the same as before as indicated by the following equation (initial momentum is the sum of all the momentum existing in the system). This principle is similar to the law of conservation of energy. Although momentum conservation and momentum conservation merely show that the momentum of the system is the same, even if there are collisions and interactions in the system, the overall force does not change. Since the momentum is mass velocity again, the mass is usually a kilogram, a speed of several meters per second. Okay, if you have seen the ball on the billiard table, you will observe this.
