WebJan 15, 2024 · With careful measurements of the work done on a system and careful measurements of the temperature of the system he was able to show that mechanical work was proportional to heat. It turns out that this is a general principle. For example, not only mechanical work but electrical work can also change thermal energy. WebTotal mechanical energy is defined as. M = K + U. where K = 1 2 m v 2 and U = m g h. No matter which direction the object is moving K must be positive due to the v 2. (I am assuming that mass is also never negative.) Potential energy is also positive because g = 9.8 and height is a distance, which is also non-negative.
