WebSep 27, 2005 · 4. A car slows down as a result of air friction. Which is true? Choices: a) The car's kinetic energy decreases. ***** b) Heat is generated. c) The energy of the car/road/air system is constant. d) all of the above e) none of the above any help is appreciated. Thank you. WebThis is a result of the law of conservation of energy, which says that, in a closed system, total energy is conserved—that is, it is constant. Using subscripts 1 and 2 to represent initial and final energy, this law is expressed as. K E 1 + P E 1 = K E 2 + P E 2. Either side equals the total mechanical energy. gatwick to liberia costa rica flight timeWebenergy transfer, the change of energy from one form to another. According to the first law of thermodynamics, energy can be neither created nor destroyed; in other words, the total energy of the universe remains constant.
