| 摘 要： | 指出若将能量（包括动能）、动量都理解为相对论中的能量和动量，则牛顿力学中的功能原理、动能定理、动量定理、牛顿运动定律及力对物体所作的功率、能量－动量守恒定律及其守恒条件在相对论中都是协变的，并给出了它们的协变形式。

| Abstract: | It is pointed out that the work energy principle, the kinetic energy theorem, the momentum theorem, the Newton's law, the power of force, the law of conservation of energy momentum and the conservative condition in the classical mechanics are all covariant in the theory of relativity if energy(including kinetic energy)and momentum are all understood as energy and momentum in the theory of relativity. |
