Term
 Simplest Model
Definition
 point objects
Term
 2 requirements for models
Definition
 1. Simple enough to be solvable2. realistic enough to be useful
Term
 What do we do in order to describe the motion of n object in mathematical language?
Definition
 In order to describe the motion of n object in mathematical language we have to introduce the model of the object, simplifying complicated situations.
Term
 Classical Mechanics
Definition
 The study of matter, motion, fores, and energy. It describes the motion of objects that are:1. Large compared with the dimensions of atoms (10^-10 m)2. Moving at speeds that are low compared of the speed of light (c = 3x10^8 m/s)
Term
 Relativity
Definition
 Describing particles moving at any speed, even those whose speed approach the speed of light.
Term
 Thermodynamics
Definition
 deals with heat, temperature, and the behavior of large numbers of particles.
Term
 Electromagnetism
Definition
 Involves the theory of electricity, magnetism, and electromagnetic fields.
Term
 Quantum Mechanics
Definition
 a theory dealing with the behavior of submicroscopic particles.
Term
 Physical Quantities
Definition
 Anything you can measure or calculate in physics
Term
 What should you be concerned with in the study of mechanics?
Definition
 We should be concerned with physical quantities (units),these can be described in terms of three fundamental quantities:1. Length (L); SI unit m2. Time (T); SI unit s3. Mass (M); SI unit kg
Term
 A scientific fact is...?
Definition
 A scientific fact is a guess that has been tested over and over again and always found to be true.
Term
 A theory is...?
Definition
 A theory is a synthesis of a large collection of information including well-tested guesses.
Term
 A precise measurement is one that?
Definition
 as exact as possible
