Term | Definition |
---|---|
Conservation in a Nuclear Reaction | 1. Mass-energy 2. Charge 3. Momentum |
Anti-Particle | Particle with the same mass opposite charge. Positron is the electrons anti-particle. |
Pair Production | A particle and its anti-particle are produced from energy bombarding matter such as lead. |
Pair Annihilation | When a particle and its anti-particle join together and are annihilated to produce energy. |
Fundamental Forces of Nature | 1. Strong Nuclear Force 2. Electromagnetic Force 3. Weak Nuclear Force 4. Gravitational |
Hadrons | Particles that feel the strong nuclear force. Baryons and Mesons. |
Baryons | Particles that have a mass greater than/equal to a proton and are composed of 3 quarks. |
Mesons | Particles that have a mass less than a proton and are composed of a quark and an anti-quark. |
Leptons | Elementary particles that do not feel the strong nuclear force. |
Quarks | Elementary particles that the baryons and mesons are made up of. |
