conservative force

  • 保守力：指一个受到某作用力的粒子，从初始位置移动到终结位置，而此作用力所做的功跟移动路径无关。等价地说，假设一个粒子从某位置，移动经过一条闭合路径后，又回到原本位置，则作用于这粒子的保守力所做的机械功（保守力对于整个闭合路径的积分）等于零。在一个物理系统里，所有的作用力都是保守力，则称此物理系统为“保守系统”，又称为“守恒系统”。重力是一种保守力，而摩擦力是一种非保守力。

双语例句

  1. Mechanical energy is conserved, because gravity is a conservative force.
    机械能是守恒的，因为重力是守恒力。
  2. It should make no difference because gravity is a conservative force.
    这没有区别,因为重力恒定。
  3. And mechanical energy is only conserved if the force is a conservative force.
    机械能只有在，力是恒定时才恒定。

英英释义

  • A conservative force is a force with the property that the work done in moving a particle between two points is independent of the path taken.HyperPhysics - Conservative force Equivalently, if a particle travels in a closed loop, the net work done (the sum of the force acting along the path multiplied by the distance travelled) by a conservative force is zero.
