(a) Mechanical energy = KE + PE. (b) It is the general name of electic and magnetic energies.
The energy possessed by a body due to its state of rest or state of motion is called mechanical energy.

Quantum mechanics is the field of physics that explains how extremely small objects simultaneously have the characteristics of both particles (tiny pieces of matter) and waves (a disturbance or variation that transfers energy). Physicists call this the “wave-particle duality.” Wave-Particle Duality ...
- 《International Journal of Modern Physics B》 被引量: 23发表: 2012年 Anharmonicity and quantum effects in thermal expansion of an Invar alloy At low temperature, the quantum effect is found to play an essentially important role, which is confirmed by comparing the quantum-mechanical simulations...

Basic Overview of Newtonian Physics 牛顿物理学概要 Explore the famous laws and principles that Sir Isaac Newton developed and derived by his unparralleled power of observation and his mechanical thought process. 艾萨克·牛顿爵士以他非比寻常的观察力和思考力提出的力学定律和原理。 》Review Historical ...
In mechanics, degrees of freedom (DOF) is the number of independent variables that define the possible positions or motions of a mechanical system in space. DOF measurements assume that the mechanism is both rigid and unconstrained, whether it operates in two-dimensional or three-dimensional space...
In physics and engineering,mechanical advantage (MA)is the factor by which a machine multiplies the force put into it. The mechanical advantage can be calculated for the followingsimple machinesby using the following formulas: Lever: MA = length of effort arm ÷ length of resistance arm. ...
Mechanics of Solids - CVNG 1000, UWI (2007/08), by r clarke 1Introduction – What is "Mechanics of Solids?" Mechanics (Greek Μηχανικ) is the branch of physics concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effect of ...
