Can heat energy change to mechanical energy
WebThe term "thermal energy" is used loosely in various contexts in physics and engineering. It can refer to several different well-defined physical concepts. These include the internal energy or enthalpy of a body of matter and radiation; heat, defined as a type of energy transfer (as is thermodynamic work); and the characteristic energy of a degree of … WebIn certain situations there is a relationship between that work and mechanical energy (as opposed to heat or radiant energy). When you accelerate an object, you are doing work against inertia, such that the work equals the change in kinetic energy of the object. Change in KE means you have accelerated the object.
