physics partial Flashcards
physics has been classified in two broad branches
Classical physics
Modern physics
classical physics
developed in ancient times with aristotle
mid 19 century with Isaac newton and Michael Faraday
Acquired knowledege was developed taking as one of the main sources of information some of the senses (sight, hearing, touch)
subdivisions of classical physics
optics
acoustics
thermodynamics
mechanics
what studies the subdivisions of classical physics
phenomena of nature related to the senses
when did the modern physics began
at the end of 19 century
branches of modern physics
quantum physics, relativity, atomic physics
Study the movement of bodies in general
mechanic physics (classical)
Study the sound and its characteristics
acoustic (classical)
Study of light and its propagation
optics (classical)
Study of heat and its transformations to others forms of energy
thermodynamics (classical)
Study of electric charges, the magnetics fields and their interactions
electromagnetism (classical)
Study of the movement of bodies at comparable speeds with that of light
relativistic physics (modern)
Study of particle movement in its wave behavior or of the movement of the waves in its behavior as particles
quantum physics (modern)
Study of the atom, its composition and properties
atomic physics (modern)
Study of the atomic nucleus, its components and forces involved
nuclear physics (modern)
Study of the classification of all particles that make up matter to conform a standard model
physics of particles (modern)
Study of plasma as a state of the matter of great energy
plasma physics (modern)
difference between classical and modern physics
classical physics has a field of observation limited to sensory perceptions of man while in modern physics it is broader
method of study in physics
the experimental scientific method
aristotelian model
the idea of order, finding the order of things (16 century)
theory of the four elements
classic (mechanistic or Newtonian) model
science focused on the search for the mechanical cause of observable phenomena (17,18,19 century)
modern model
primodiral concept the probability that matter has certain behavior at a microscopic level (20 century)
great contrubtion of galileo
use the measurements for the analysis of the phenomena, introduced the mathematical language
how galileo measured time
with a system of dripping water
physical magnitudes are classified as
fundamental and derived
fundamental physical magnitude
do not depend on any other physical magnitude and are measured directly
fundamental physical quantities
length mass time temperature amount of substance luminous intensity current intensity
derived physical magnitudes
formed by the combination of two or more fundamnetall physical quantities
derived physical quantities
area volume speed acceleration force work power
unit of measurement of length
metre (M)
unit of measurement of mass
kilogram (kg)
unit of measurement of time
second (S)
unit of measurement of temperature
kelvin (K)
unit of measurement of amount of substance
Mole (Mol)
unit of measurement of luminous intensity
candle (Cd)
unit of measurement of current intensity
Ampere (A)
physical quantity
the result of as measurement , quantifications of the properties that we want to measure.
systems of weights and measures
International system (SI) CGS system (system cegesimal) english system
the study of the types of movement that a body can have and its mathematical description
kinematic
change in position in the space and through time
movement
the space traveled by the body during the change of position
distance
it is the movement to move from one place to another
displacement
the realtionship that is stablish between the space or the distance that travel an object an the time it invests in ot
speed-rapidity
change in speed of a body during its movement
acceleration
property of all bodies to resist changes in their state
mass
every agent capable of producing a change in the movement of a body
force
in the force with wich the earth attracts a body due to the action of gravity
weight
length measuring objects
ruler
tape measure
flexometer
nonio (known as caliper)
mass measurement instruments
roman scale arms
electronic scale
instruments for measuring time
shadow cast (ancient) sun (ancient) mechanical clock digital chronometer atomic clock
