Conservation Of Momentum And Collisions Definition
Conservation, in physics, refers to something that cannot be changed, or which remains constant. If variable quantities are required to be considered, then variable defines conserved quantity which remains constant over time. The value must remain same before the event and after the event. When mechanics are to be dealt with, three quantities are used in fundamental physics. The three quantities named energy, momentum and angular momentum remain conserved. Conservation of momentum states that momentum must remain conserved before and after the collision.

Overview of Conservation Of Momentum And Collisions
Conservation of momentum is mostly used to describe the collision that occurs between the objects. The momentum remains conserved in the case of isolated system dealing with the objects. Isolated system is that system in which no external force is acting upon the system and thus, initial and final momentum will be the same. For the two objects in the isolated system, when collision occurs, the total momentum occurred before the collision is equal to the total momentum occurred after the collision. Collision is of two types: Elastic and Inelastic collision. Elastic collision is that collision in which kinetic energy before the collision is equal to kinetic energy after the collision. Inelastic collision is that collision in which kinetic energy is not conserved.

Inelastic collision: It is that collision in which there is conservation of momentum but there is no conservation of total kinetic energy. In the case of inelastic collision, some amount of kinetic energy is wasted and gets deformed and converted into thermal energy. The impulsive forces do not get conserved in inelastic collision. The collision is considered as inelastic if kinetic energy before collision is less than the kinetic energy after the collision.

When mechanics are to be dealt with, three quantities are used in fundamental physics. The three , momentum and angular momentum remain conserved. Conservation of momentum states that momentum must remain conserved before and after the collision.

Conservation of momentum is mostly used to describe the collision that occurs between the objects. The in the case of isolated system dealing with the objects. Isolated system is that system in which no is acting upon the system and thus, initial and final momentum will be the same. For the two objects in the isolated system, when collision occurs, the before the collision is equal to the total momentum occurred after the collision. Collision is of two types: Elastic and Inelastic collision. Elastic collision is that collision in which kinetic energy before the collision is equal to kinetic energy after the collision. Inelastic collision is that collision in which kinetic energy is not conserved.

The principle of conservation of momentum depends upon Newtons third law of motion. It is well known that Newton third law of motion states that to every action, there should be equal and opposite reaction. Suppose there are two objects, say object 1 and object 2.

When collision between the two objects occurs, force will act on object 1 due to object 2 that is, F_{12}F
12

. In return, because of Newton third law of motion, object 2 exerts equal force but with opposite direction on object 1 that is, -F_{21}F
21

. This can be more generalized with the help of an equation which states that,

{F_{12}} = – {F_{21}}F
12

=F
21

Thus, momentum remains conserved but with equal and opposite forces. For the two objects, when force is being applied, the force acts for certain period. The time can be short or long, regardless of these facts, the time exerted by object 1 due to object 2 is equal to the time exerted by object 2 due to object 1. So, mathematically, it can be written as:-

T_{12}=T_{21}T
12

=T
21

As the time for these forces must remain same, the impulse exerted upon the object is defined as the momentum change upon the object. So, the momentum change between the objects will be equal but with the opposite directions. So, the equation is written as follows:

m_1Delta v_1=-m_2Delta v_2m
1

v
1

=m
2

v
2

Thus, it can be also written as,

m_1Delta v_1+m_2Delta v_2=0m
1

v
1

+m
2

v
2

=0

The law of conservation of momentum can be applied if the that acts upon the system will be zero. The condition that this law of conservation of momentum follows is,

Sigma F_{rm external}=0
