机械能(Mechanical Energy)是物体的动能与势能之和。 -动能(Kinetic Energy, KE):物体运动产生的能量。12mv2 -势能(Potential Energy)是物体由于高度或位置具有的能量。最常见的是重力势能(Gravitational Potential Energy)。 机械能守恒定律指出: 在一个理想系统(无摩擦和空气阻力)中,若只有
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...
在分子动力学模拟中,系统的总能量可以分解为动能(kinetic energy)和势能(potential energy)两部分。 动能是由于分子的运动而产生的能量。根据经典力学,分子的动能可以通过它们的质量和速度来计算。动能与分子的速度平方成正比,即 动能= 1/2 mv^2 其中,m为分子的质量,v为分子的速度。 势能是由于分子之间相互作用而...
Kinetic energy is the energy of motion. Potential energy is converted to kinetic energy when the object in question begins to move. There are three types of kinetic energy: vibrational, rotational and translational. Each type of kinetic energy is named according to the type of movement the objec...
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).
Learn about kinetic and potential energy and study the relationship between the two. Compare kinetic vs. potential energy examples and understand...
Kinetic 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). Potential energy changes to ...
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 ...
