This article is a glossary of classical physics. It is some of the most common terms in classical physics and how they are used.

A[edit]

B[edit]

C[edit]

D[edit]

  • Determinism – classical physics is largely deterministic
  • Dip (δ) – the angle between magnetic meridian and geographical meridian.

E[edit]

  • Elastic collision – a collision during which no kinetic energy is lost
  • Electric current – the flow of electric charge through an object
  • Electrical resistance – a measure of the degree to which an object opposes the passage of electric current
  • Energy – a measure of being able to do mechanical work
  • Electromotive force – the amount of energy gained per unit charge that passes through a device in the opposite direction to the electric field existing across that device
  • Eddy currents – changing magnetic flux linked with metal plate produces induced current which flow in closed paths throughout the body of the metal

F[edit]

G[edit]

  • Gravity – an attractive force between particles with mass
  • Geomagnetism – the branch of physics which deals with the study of earth's magnetic field

H[edit]

I[edit]

  • Ideal gas – a gas consisting of identical particles of negligible volume, with no intermolecular forces
  • Inertia – a historical concept of resistance offered by objects to external force when applied

J[edit]

  • Joule's law – equation for the heat generated by a current flowing in a conductor

K[edit]

L[edit]

  • Lagrangian – a function describing the equations of motion for a system
  • Lagrangian mechanics – an abstract reformulation of classical mechanics
  • Light – a form of energy, which causes sensation of sight

M[edit]

  • Macroscopic – attribute used for objects and processes observable by the naked eye
  • Mass – a measure of the amount of matter
  • Maxwell's equations – four equations that describe electric and magnetic fields, and their interaction with matter
  • Molecule – a group of atoms joined by chemical bonds
  • Momentum – the product of mass and velocity
  • Magnetic field – the space around a magnet or a current within which its magnetic influence can be detected or experienced

N[edit]

O[edit]

  • Ohm's law – relationship between the current flowing in a conductor and the voltage difference between its ends

P[edit]

Q[edit]

R[edit]

  • Resonance – the tendency of a system to absorb more energy at its resonance frequency in a given process

S[edit]

T[edit]

  • Temperature – the average kinetic energy of molecules
  • Thermodynamics – the study of thermal processes in physical systems

U[edit]

V[edit]

  • Velocity – the rate of change of position with respect to time.

W[edit]

  • Wave – a disturbance that propagates in a periodically repeating fashion, often transferring energy
  • Work – energy transferred by a force

X[edit]

  • X-rays – a form of ionizing electromagnetic radiation and magnetical ambiance's

Y[edit]
