Ephys ch 1 Flashcards
is the major science dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces.
physics
The scientific study of matter, energy, force and motion and the way they relate to each other
physics
is the study of subatomic particles and their combinations in atoms and molecules.
microphysics
refers to areas of physics that study phenomena that take place on the microscopic scale
microphysics
phenomena that take place in microscopic scale are (6)
quantom mechanics

atomic physics
nuclear physics
particle physics
nanotechnology
study of large collections of subatomic particles such as the solid bodies of everyday experience.
macrophysics
branch of physics that deals with the physical objects large enough to be observed and treated directly
macrophysics
8 branches of physics
mechanics
heat
thermodynamics
electricity
magnetism
optics
acoustics
modern physics
oldest branch of physics
mechanics
deals with the study of the bodies and systems and the forces acting on them.
mechanics
branch of mechanics concerned with the analysis of loads on physical systems in static equilibrium
statics
the system is either at rest or its center of mass moves at constant velocity
static equilibrium
branch of mechanics that is concerned with the effects of forces on the motion of a body or system of bodies especially of forces that do not originate within the system itself
dynamics
it is the forces and motions that characterize a system
dynamics
branch of physics which studies the principle of the energy associated with the kinetic random motion of large numbers of molecules.
heat
includes the principle of temperature measurement, the effect of temperature change on the properties of materials and heat flow
heat
the study of transformation of energy
thermodynamics
describes and correlates the physical properties of macroscopic systems of matter and energy
thermodynamics
the principls of ____ are pf fundamental importance to all branches of science and engineering
thermodynamics
the branch of physics which deals with the study of electric charges at rest or in motion
electricity
electric charges at rest
electrostatic
electric charges in motion
electrodynamics
it is a manufactured product and is not something you pump out of the ground or mine or collect from the sun or wind
electricity
is manufactured from a rotating machine that we call an electrical generator.
electric power
is a phenomenon in which one body exerts a force on another body with which it is not in contact
magnetism
the force where objects are attracted or repelled to one another
magnetism
the branch of physics concerned with light and vision
optics
deals with the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.
optics
refers to geometry of light rays as they pass through an optical system
geometrical optics (ray optics)
describes light propagation in terms of “rays”
geometrical optics (ray optics)
is an abstraction or instrument that can be used to predict the path of light
ray
is the properties of light and its interaction with matter
physical optics (wave optics)
branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid
physical optics (wave optics)
is the branch of physics concerned with the production, propagation, reception properties, and uses of sounds.
acoustics
it is the interdisciplinary science that deals with the study of sound, ultrasound and infrasound
acoustics
is the branch of physics which studies the modern aspects of the subjects, which include quantum mechanics and astrophysics.
modern physics

metric conversion act of 1975
is the amount of matter that a body contains
mass
measure of the inertial property of that body
mass
measure of the attraction of the earth for a given mass
weight
is the measure of distance or duration of time
length
refers to the conscious experience of duration
time
the period during which an action or event occurs
time
dimension representing a succession of such actions or events
time
the amount of space occupied by a solid figure
volume
