动能

• The released electron is accelerated by the applied field and gains kinetic energy .
  被释放的电子在施加的电场的加速下获得动能。
• The larger the mass m, the smaller the kinetic energy associated with a given momentum .
  质量M愈大，则与给定动量相关联的动能就愈小。
• At first glance this bears no resemblance to the classical definition of kinetic energy .
  初看起来，它与动能的经典定义毫无相似之处。
• In computing the kinetic energy of a body, consistent units must be used for m and v .
  在计算物体的动能时，对m和v必须使用适当的单位。
• These components are known as the zonal kinetic energy and eddy kinetic energy respectively .
  这两部分能量分别称作纬向动能和涡旋动能。
• The sum of the kinetic and potential energy of the body is called its total mechanical energy .
  物体的动能和势能之和称为物体的总机械能。
• Both the momentum and kinetic energy of the first are completely transferred to the second .
  第一个物体把它的动量和动能全部传递给第二个物体。
• The minus sign indicates that the work done by the force decreased the kinetic energy of the neutron .
  负号表明这个力所作的功降低了中子的动能。
• If only conservation forces act, the kinetic energy plus the potential energy remains constant .
  如果只受保守力的作用，则动能加势能是一个恒量。
• The energy, dissipated in this way, will finally appear as energy of molecular motion or heat .
  以这种方式损失的能量最终表现为分子的动能或热能。
