come readily to mind are the effects on the human body‚ thermodynamics and plate tectonics. Without friction‚ many functions of the human body would not work. Procreation would be impossible as friction is necessary for the male orgasm. Digestion would be impossible as the human body uses friction to digest and move food throughout the body. Under conditions where the coefficient of friction is 0 on all surfaces‚ the laws of Thermodynamics would be useless (Goulding). Since friction creates heat

First Law of Thermodynamics The first law of thermodynamics states that the energy cannot be created nor destroyed it can only be changed from one form to another. Another name for this law is the law of conservation of energy. This means that the total energy of a system plus its surroundings is constant and does not change. Energy can‚ however‚ be transferred in or out of the system and to or from the surroundings through work or heat. Conservation of Energy Energy may be defined as the

Free energy‚ naphthalene II. Introduction Enthalpy‚ H‚ is a thermodynamic property of a system. It is defined as the sum of internal energy U of a system and the product of the pressure and volume of the system: H = U+PV The PV term represents the mechanical work done on or by the system. Since we are usually more interested in changes than in absolute values‚ we could write ΔH = ΔU+PΔV Entropy‚ S‚ is an another thermodynamic property.‚ which we can consider as a measure of the disorder or

JAMES PRESCOTT JOULE James Prescott Joule was one of the most famous physicists in England in the 17th Century. On the 24th day of December 1818‚ Joule was born near Manchester‚ England in a wealthy business-owning family with five children. As a child‚ he suffered from a spinal disorder which caused him to become shy and weak. Unlike those of his age‚ he preferred to stay indoors and learn‚ instead of playing in the field. As expected by his parents‚ James and his brother were to inherit the
