The laws that are used in Physics are the conclusions that are drawn after conducting many experiments that are now applied in day-to-day life. These laws and statements are universally accepted and cannot be altered.
Following is a list of such important laws that are used in Physics:
- Newton’s law of motion: There are three Newton’s law of motion which explains the relationship between the state of an object and to its motion.
- According to Newton’s first law of motion, an object continues to be in a state of rest until and unless an external force has been applied.
- According to Newton’s second law of motion, force is a product of mass and acceleration.
- According to Newton’s third of motion, for every action, there is an equal and opposite reaction.
- Boyle’s law: Boyle’s law states that for a given mass of gas, the temperature remains constant when the volume varies inversely with respect to the pressure of the gas.
- Charle’s law: Charle’s law states that for a given mass of gas, the pressure remains constant when the volume is directly proportional to the absolute temperature.
- Kelvin-Planck statement: According to the Kelvin-Planck statement, it is impossible to devise a heat engine which operates in a cycle and produces no other effect other than heat transfer is generated to produce work.
- Clausius statement: According to the Clausius statement, it is impossible to design a device which operates in a cycle and produce no other effect other than the heat transfer from a cold body to a hot body.
- Law of conservation of energy: The law states that the energy can neither be created nor be destroyed but can be transformed from one form to other.
- Law of conservation of mass: The law states that for an isolated system, the mass can neither be created nor be destroyed, it remains constant.
