PHY2061 Enriched Physics 2 Lecture Notes Relativity 4 Invariant Mass We can now apply the relativistic definitions of energy and momentum to calculations of particle collisions. In particular, we can compute the rest mass of a particle formed when two particles annihilate into pure energy and then form a new particle.

*Jul 26, 2017 · Impulse = Change in momentum Principal of conservation of momentum For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. That is, the momentum lost by object 1 is equal to the momentum gained ...*Conservation of Momentum In practice, for any event in an isolated system: Momentumafter = Momentumbefore The End. Ch 7 Momentum Notes Concept Summary Batesville High School Physics Momentum Momentum is what Newton called the “quantity of motion” of an object. Momentum The momentum of an object: Depends on the object’s mass.
