Physics Abc Book
Electron Accelerator A particle accelerator that is designed to speed up electrons. Flavor A set of quantum numbers that identify the type of particle it is. Gravity Gravity is the force that pulls on us at all times. Without gravity we would fly off the Earth. Hertz A unit of frequency. Ion An atom that has an electrical charge that is not equal to zero. Jet a highly directed spray of particles produced and detected in a collider experiment. Kinetic Energy The amount of energy an object due to its motion. Light-year
The distance that light travels at the same speed for a year. Macroscopic Unlike microscopic objects these can be seen without the aid of a microscope. N-body Simulation A computer simulation that uses large numbers of particles that interact according to basic physical laws. Open String Has two distinct ends. An open string can have one end attached to another object like a brain, and the two ends of an open string can connect to form to from closed sting. Potential Energy Stored energy. Quantum The smallest amount of light energy, or a basic unit of measure.
Radiation The process in which energy is sent out as particles or waves. Solution When a solid, liquid, or a gas is mixed evenly(homogeneously) without causing a chemical change. Torsion Pendulum Unlike a Conventional Pendulum a Torsion pendulum rotates. It has a mass held by a string and it rotates periodically. Uranium An element on the periodic table and is found in nature. It is white, metallic, and radioactive. It was used in one of the Atomic Bombs and Hydrogen Bombs. It is a also used as a fuel for nuclear reactors.
Vortex A region in which liquid or gas flows in a spiral toward the vortex center. Wave length The distance between two points in the wave. Often thought of when talking about sound or light. Xray A form of electromagnetic radiation. Has a shorter wave length then light and is able to go through solids and ionizing gases. Young’s Modulus the coefficient of elasticity of a solid; the rate of stress with strain. Zero point energy The minimum energy a system can have based on the Heisenberg uncertainty principle.
