GE 208K---[PHY 303K] Chapter 1: Space, Time & Mass Prepared By: Fady Morcos Chapter 1: Space, Time & Mass Ideal particle: Particle with point mass. o At any point in time, the particle occupies a single point in space. o Position, Time and Mass give complete description of the behavior and attitude of an ideal particle. o Position, Time and Mass are often referred to as fundamental dimensions. Coordinates and Reference Frames o Coordinate Frame: A Frame or a Grid used to define the position of a particle relative to some origin O. s e.g. Cartesian/Rectangular, polar, spherical…etc o Reference Frame: Coordinate grid with an array of synchronized clocks. s e.g. Trajectory: x-y position as function of time. The Unit of Length o Need to define three fundamental dimensions: Distance, Time & Mass. o Can express our measurements as numerical multiples or fractions of fundamental dimensions. o 1 meter = dist. travelled by light in vacuum in a time interval of 1/299792458 seconds. s
