In mechanics and physics, simple harmonic Oscillation is a type of periodic motion where the restoring force is directly proportional to the displacement. It can serve as a mathematical model of a variety of motions, such as the oscillation of a spring. In addition, other phenomena can be approximated by simple harmonic Oscillation, including the … Read more
Last Updated: March 19, 2026 at 8:54 pmWhen an elastic material is deformed due to an external force, it experiences internal forces that oppose the deformation and restore it to its original state if the external force is no longer applied. There are various elastic moduli, such as Young’s modulus, the shear modulus, and the bulk modulus, all of which are measures … Read more
Last Updated: March 19, 2026 at 8:54 pmIn physics, a fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasma and, to some extent, plastic solids. Although the term “fluid” includes both the liquid and gas stages, in common usage, “fluid” is often used as … Read more

Last Updated: March 19, 2026 at 8:54 pmTemperature is a physical quantity that is a measure of hotness and coldness on a numerical scale. It is a measure of the local thermal energy of matter or radiation; it is measured by a thermometer, which may be calibrated in any of various temperature scales, Celsius, Fahrenheit, Kelvin, etc., etc. Empirically it is found … Read more

The first law of thermodynamics is a version of the law of conservation of energy, specialized for thermodynamical systems. It is usually formulated by stating that the change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the … Read more
