While conservation of momentum is universally correct, it is primarily used in physics to describe what...
Due to Umklapp phonon scattering, the conservation of momentum is broken. Why does the conservation of momentum break for Umklapp scattering of phonons? One assumption could be that phonons are quasi-particles, and hence the conservation of momentum does not matter and does not apply. If this is true, what are the further explanations/implications of this assumption. If not, what are other possible explanations to describe the loss of the extra momentum that is not accounted for in Umklapp scattering?
Introduction: In this lab you will investigate the conservation of linear momentum: momentum before an event equals momentum after an event if there is an absence of a non-conservative forces such as friction. The event is this case is a collision between two air track gliders. Two types of collisions will be studied. One is an elastic collision which will not be studied in this lab. after the collision. The second is an inelastic collision where after two objects collide,...

1. Use the conservation of momentum to discuss what happens to a passenger in a car crash. Discuss the use of a seat belt in bringing the passenger to rest. 2. You are watching a movie about a superhero and notice that the superhero hovers in air and throws a piano at some bad guys while remaining stationary in the air. What is wrong with this picture?
