field physics


Physics is related to mathematics, which provides the logical framework in which physical laws are precisely formulated. Physical definitions, models and theories are always expressed using mathematical relations.
A key difference between physics and mathematics is that physics is ultimately concerned with descriptions of the material world, therefore physical theories are tested by observations (called experiments), whereas mathematics is concerned with abstract logical patterns not limited by those observed in the real world. There is still a large area of research intermediate between physics and mathematics, known as mathematical physics.
Physics is also closely related to engineering and technology: electrical engineering is the study of the applications of electromagnetism; mechanics is the branch of physics that studies the behaviour of physical bodies when subjected to forces or displacements, while statics is concerned with the analysis of loads on physical systems in static equilibrium.
Thermodynamics deals with the action of heat and the conversion of energy from one form into another; thermodynamics is particularly concerned with temperature, pressure, volume, mechanical action, and work.
