The potential energy is converted to kinetic energy ___ the object falls. A. while B. before C. after D. as 相关知识点: 试题来源: 解析 D。“当物体下落时,势能转化为动能”,as 表示“当……的时候”,符合语境。while 通常表示“在……期间”,强调动作同时进行;before 表示“在……之前”;...
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). Potential energy changes to kinetic energy when the object moves. Ex...
When energy is transformed from potential energy to kinetic energy, what happens to the object? A. It stops moving. B. It moves slower. C. It moves faster. D. It remains at the same speed. 相关知识点: 试题来源: 解析 C。解析:当能量从势能转化为动能时,物体的速度会变快。物体停止运动...

Potential energy that is not so obvious as kinetic energy exists in many things. A.许多事物中都包含不如动能明显的势能。B.不如动能明显的势能存在于许多事物中。C.势能虽然不像动能那样明显,但它存在于许多物体之中。D.当势能不像动能那样明显时,便可在许多物体中找到它。
kinetic energy = electron volts? The Attempt at a Solution I tried to first calculate the electron volts: 330V (J/C) * 3.20E-19C = 1.056E-16 V I know this electrical potential energy is converted into kinetic energy, but I'm not sure how to factor in the distance between the plates...
kinetic energy, using the Lego Mindstorm kit. Potential energy is a form of stored energy that can be converted to kinetic once the object or system is set in motion. For example, when a roller coaster is at the top of the hill, the system has in within it potential energy. As the ...
Potential energy of a body is by virtue of its position or shape whereas kinetic energy of a body is by virtue of its motion.
In review, energy is the capacity to do work, and work is accomplished when a force moves an object. Energy exists in different forms, all of which can be classified as either potential energy or kinetic energy. Potential energy is energy stored in an object due to its position or...
