Physics Exam 1: Review
Mechanics - correct answer motion and its causes, interactions between objects
Ex. falling objects, friction, weight spinning objects
Thermodynamics - correct answer heat and temperature
Ex. Melting and freezing, processes, engines, refrigerators
Vibration and Wave Phenomena - correct answer Specific types of repetitive
motions
Ex. springs, pendulums, sound
Optics - correct answer light
Ex. mirrors, lenses, color, astronomy
Electromagnetism - correct answer electricity, magnetism, and light
Ex. electrical charge, circuitry, permanent magnets, electromagnets
Relativity - correct answer Particles moving at any speed, including very high speeds
Ex. Particle collision, particle accelerators, nuclear energy
Quantum Mechanics - correct answer behavior of submicroscopic particles
Ex. the atom and its part
Model - correct answer a pattern, plan, representation, or description designed to
show the structure or workings of an objects, system, or concept
System - correct answer a set of particles or interacting components considered to
be a distinct physical entity for the purpose of study.
, Hypothesis - correct answer an explanation that is based on prior scientific research
or observations and that can be tested
Controlled Experiment - correct answer an experiment that tests only one factor at
a time by using a comparison of a control group with an experimental group
10^-9 - correct answer nano (n)
10^-6 - correct answer micro (u)
10^-3 - correct answer milli (m)
10^-2 - correct answer centi (c)
10^3 - correct answer kilo (k)
10^6 - correct answer mega (M)
Accuracy - correct answer a description of how close a measurement is to the
correct or accepted value of the quantity measured
Precision - correct answer the degree of exactness of a measurement
Significant Figures - correct answer those digits in a measurement that are known
with certainty plus the first digit that is uncertain
Rule 1 to determine the sig figs - correct answer Zeros between other non-zerodigit
are significant
Ex: 50.2 - 3 ; 3.0025- 5
