Mechanics is the branch of Physics dealing with the study of motion when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. This mechanics subject has three branches
- Classical Mechanics
- Quantum Mechanics
- Statistical Mechanics
In this article will read about Statistical Mechanics
Statistical mechanics is the branch of the theory of physics, examining the use of probability theory and also the average or mean behaviour of a mechanical system wherein the state of the system is said to be uncertain. This branch of statistical mechanics that treats and extends classical thermodynamics is known as statistical thermodynamics or equilibrium statistical mechanics. The common use of this machine is in the thermodynamic accomplishment of large systems.
Features of Statistical Mechanics
- The science of statistical mechanics has the unique function of providing a reasonable method for treating the behaviour of mechanical systems under circumstances such that our knowledge of the situation of the system is less than the maximal knowledge which would be theoretically possible.
- The principles of ordinary mechanics may be observed as allowing us to make precise predictions as to the future state of a mechanical system from a precise knowledge of it is initial state.
- On the other hand, the principles of statistical mechanics are to be considered as permitting us to make reasonable predictions as to the future condition of a system, which may be expected to hold on the average, starting from an incomplete knowledge of it is the initial state.
