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...
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...
the sum of the two, it always stays the same.Energy of a pendulumAt the highest point of the swing (S), kinetic energy is 0 and potential energy is its highest.At the lowest point on the swing (Q), potential energy is 0 and kinetic is its highest.Where is kinetic energy the most...
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).
Kinetic energy is the energy that an object possesses due to its motion. It is dependent on the object's mass and velocity. When an object is in motion, it has the ability to do work and transfer energy to other objects or systems. The faster an object moves or the greater its mass,...
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 ...
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...
