Ideal gas - an idealised version of a gas obeying the gas laws at all pressures, volumes and temperatures

Impulse - the product of force and the time interval for which the force acts; it equals the change in momentum

Inertia - the tendency of a massive body to remain in its current state of motion

Instantaneous speed - the speed at an instant of time; the rate of change of distance with time

Instantaneous velocity - the velocity at an instant of time; the rate of change of displacement with time

Insulator - an object or material which electric current cannot pass through

Intensity - power of radiation per unit area; power per unit

Interaction vertex - a building block of Feynman diagrams representing a fundamental interaction process

Internal energy - the total random kinetic energy and interrnole cular potential energy of the molecules of a substance

Inverse  square  law - a law where a physical quantity is inversely proportional to the square  of the  distance  from the source of that quantity; intensity of light from a source obeys an inverse square law
