摘　　要：通过动能定理及相对论质量公式,对相对论动能公式进行了推导,并指出速度接近低速时,该公式过渡为一般动能公式,速度接近光速时,物体所有能量转化为动能。The energetic formula in theory of relativity was given out with the help of energetic theorem and mass formula in theory of relativity and the energetic limit was reported. When the velocity was lesser, the energetic formula in theory of relativity was transform into energetic formula in Newton mechanics, but when the velocity approached to c, all energy was conversion to the kinetic energy.

关 键 词：相对论 动能公式 相对论质量公式 极限
