m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
Where:
* m₁ and m₂ are the masses of the two objects involved
* v₁ and v₂ are the initial velocities of the two objects
* v₁' and v₂' are the final velocities of the two objects
Explanation:
This equation states that the total momentum of a closed system (a system where no external forces act) remains constant before and after a collision or interaction. In simpler terms, the total momentum of the objects before the interaction is equal to the total momentum of the objects after the interaction.
Key points:
* Momentum is a vector quantity, meaning it has both magnitude (mass times velocity) and direction.
* The law of conservation of momentum applies to collisions, explosions, and any other interaction where no external forces act.
* The equation can be generalized to include any number of objects.
