Resistance - Physics

Physics

  • Electrical resistance, a measure of the degree to which an object opposes an electric current through it
  • Friction,
    • Drag (physics) ("air resistance"), fluid or gas forces opposing motion and flow
  • Geological resistance, a measure of how well minerals resist erosive factors
    • Hydraulic conductivity, the ease with which water can move through pore spaces or fractures in soil or rock
  • Thermal resistance, a measure of difficulty of heat transfer through a substance
    • Thermal conductivity, how well heat is conducted through a substance
    • Thermal resistance in electronics, heat considerations in electronics design
  • In materials science, the term is sometimes used for hardness

Famous quotes containing the word physics:

    He who is conversant with the supernal powers will not worship these inferior deities of the wind, waves, tide, and sunshine. But we would not disparage the importance of such calculations as we have described. They are truths in physics because they are true in ethics.
    Henry David Thoreau (1817–1862)

    The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.
    Erich Fromm (1900–1980)

    The fundamental laws of physics do not describe true facts about reality. Rendered as descriptions of facts, they are false; amended to be true, they lose their explanatory force.
    Nancy Cartwright (b. 1945)
