Glossary of Physics (I)

 
Ice-point: The melting point of ice under 1 atm pressure, it is equal to 0 or 32.
Ideal gas Equation: PV = nRT
Impulse: The product of force and time for which force acts, also equal to the change in momentum.
Inertia: The property of a body to resist a change in its state of rest or of uniform motion.
Infrasonic: Sound waves of frequency less than 20 Hz, below the range of human hearing.
Insulators: Materials like wood that are poor conductors of heat or electricity.
Interference: The redistribution of energy due to superposition of waves from coherent sources, resulting in alternate light and dark bands.
Internal energy: Sum of the kinetic energy and potential energy of all molecules of an object.
Isobaric process: In which pressure remains constant.
Isochoric process: In which volume remains constant.
Isothermal process: In which temperature remains constant.
Isotope: atoms of the same element with same atomic no (no of protons) but different mass no (no of neutrons)
