Law of conservation of momentum and collision [solve].Momentum the treasure will be special is that conservation is always (increase, and at the same time, it does not reduce the lost) even in the crash. The kinetic energy that will not be conservative in the collision. If a collision is not elastic collision Due to the stability of the momentum that mentioned. It can be calculated the speed at which realize the value after the collision.Problems in physics that have used the fact that speak of. Is the collision of two particles. The sum of the momentum before the collision must equal the sum of the momentum after the collision.M_1 mathbf V _ {,} + 1 I m_2 mathbf V _ I}, {2 = m_1 mathbf V _ {,} + 1 f m_2 mathbf V _ 2 F} {,,The subscript i shows before a collision and subscript f shows after the crash.Usually, we only know the speed before collision, or after the collision, not either one and want to know the speed of the other one. To solve this problem properly will make us know the people, that is how the collisions that have two types as follows.Elastic collisions, as the collision energy conservation.Inelastic collision was a collision does conservation energy.Both types of collisions that mentioned this It was a smash that conserve momentum.
