Another form of kinetic energy is heat: the total kinetic energy of all moving atoms,ion, or molecules within a given substance,excluding the overall motion of the whole object. When two objects at different temperatures contact, heat flows form the warmer object to the cooler object.
另一種用動能形成的能量是熱:所有移動的原子,離子,或者分子內的特定物質為總動能,但不包括整個行動的物體。當兩個不同物體在不同的溫度相互接觸下,熱流動形成溫熱的物體流向較冷的物體。
