Conservation of momentum in perfect elastic collisions

Click For Summary
SUMMARY

The discussion centers on the conservation of momentum in perfect elastic collisions, emphasizing that momentum is a vector quantity and is conserved in all types of collisions, including elastic and inelastic. Participants clarify that while momentum conservation is vectorial, energy conservation is scalar and applies exclusively to elastic collisions. The distinction between vectorial and scalar conservation is crucial for understanding the mechanics of collisions.

PREREQUISITES
  • Understanding of vector and scalar quantities

I learned that momentum conservation is vectorial, and now, when i read about perfect elastic collisions, I can't understand why they use a scalar conservation. I tryed to use vectorial coervation to see the diference and it's true: it's needed a scalar conservation. But why?
 
Physics news on Phys.org
Momentum is a vector and is always conserved, whether the collision is elastic, inelastic, somewhere in-between.
Energy is a scalar and is conserved only in an elastic collision.
