DE Science Middle School Energy and Work Potential and Kinetic Energy Potential and Kinetic Energy— The Key Ideas • Energy is the ability to do work, or move an object from one position to another. All forms of energy can be considered to fall into two categories—kinetic energy and ...
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).
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。

A body is said to possess energy when it can perform work. It may possess this energy by reason of its position (potential energy, PE) or due to its condition (kinetic energy, KE). The unit of energy is the joule, which is defined as the work done when a force of 1 N is ...
