解析 B。解析:kinetic energy是动能,它与物体的运动有关,是由于物体运动而具有的能量。potential energy是势能,它与物体的位置有关,是由于物体的位置而具有的能量。所以与物体位置有关的是potential energy,A选项kinetic energy不符合,C选项both错误,D选项neither不对。
Energy is the capacity to do work.The unit of energy is J (Joule) which is also kg m2/s2 (kilogram meter squared per second squared)Energy can be in many forms! Here we look at Potential Energy (PE) and Kinetic Energy (KE).

potential energy 势能 kinetic energy 动能 当球抛向高空时、球具有动能、当球向上飞行到顶点时、球的动能就会转化为重力势能、当球向下落时、球的重力势能就会转化为动能、当球刚刚接触地面时、动能就会转化为重力势能、当球接触地面被压扁时、重力势能就会转化为弹性势能、当球从地面弹起的候、弹性势能...
Kinetic energy vs. Potential energyKinetic energy vs. Potential energy Energy is the ability to do work. Objects can have stored, or potential, energy when work has been done (such as raising an object in the air) or by virtue of their position (such as sitting at the top of a hill...
