Introduction . –. Heavy Ion Physics. Heavy ion physics seeks to understand the behavior of strongly interacting matter (quarks and gluons) at extreme temperatures and densities.. Hadronic Matter. Inelastic vs. Elastic. Pg. 233 – 239. Pg. 240 - 248. Momentum vs. Energy. All interactions conserve momentum.. They do . not necessarily. conserve kinetic energy.. Obvious example: Explosions. Kinetic energy before is zero.. Statistics. “One out of every four accidents can be blamed on poor backing techniques”. - National Safety Council. …If only trucks would bend…. Statistics. The cost of “Property Damage Crash” (a typical backing up accident) is presently estimated at an average of $7,400 per event.

The cost of “Property Damage Crash” (a typical backing up accident) is presently estimated at an average of $7,400 per event. Law of Conservation of Momentum. With no external force, momentum doesn’t change. It’s the opposite of the impulse momentum relationship!. Ft = Δmv. Example. Consider a gun being fired.. A gun recoils when it is fired. .
