The condition for the conservation of mechanical energy is that the work done by non-conservative forces must be ___. A. positive B. negative C. zero D. infinite 相关知识点: 试题来源: 解析 C。中文解析:机械能守恒的条件是非保守力做功必须为零。如果非保守力做功不为零,那么机械能就会发生...
According to the principle of conservation of mechanical energy, in the absence of non-conservative forces, the total mechanical energy of a system remains constant. What does total mechanical energy consist of? A. Kinetic energy only. B. Potential energy only. C. Kinetic energy and potential ...
statement that besides obliterating the concept of mechanical work, diminishing the importance of the work-kinetic energy theorem, leads to erroneous applications of the energy conservation theorem and at the same eliminates its relationship with the principle of the conservation of the mechanical ...
Suppose the kinetic energy of a rigid, rotating system can be expressed asK=12Iω2where I is some constant for this system. By considering the conservation of mechanical energy, find an expression for I for this system in terms of m and r. ...

The law of the conservation of energy states that energy is neither created nor destroyed. Instead, it is simply transferred from one type of energy to another, or from one form of energy to another. The difference between mechanical energy and kinetic energy is that kinetic energy is a type...
应该翻译成守恒(Conservation)力。因为In a system influenced only by conservative forces, the total mechanical energy (kinetic energy + potential energy) is conserved. This, then, could tell us the distribution of molecules: Suppose that we had a positive ion in a liquid, attracting negative ions...
