这key difference between kinetic energy and temperature是动能是指移动物体的特性,特别是从其静止状态加速身体所需的工作,而温度是热能在所有问题上都存在。
动能和温度是相关的术语,因为系统的动能可以根据该系统的温度变化而变化。例如,温度升高可以提高velocity系统中的移动颗粒,从而增加了该系统的动能。

什么是动能
这kinetic energy of an object is the energy that arises due to motion. It is the work we need to accelerate an object having a certain mass from its rest state to a particular velocity state. During the加速度of the object, it gets kinetic energy and maintains it (at the same level) until the speed changes. In contrast, the object does the same amount of work during decelerating its speed from that particular velocity to the rest state.
以“ V”速度移动的非旋转对象的动能如下;
E =½mv2
但是,当速度“ V”与光速相比非常小时,该方程非常重要。动能的测量单位是焦耳,但是测量动能的英语单元是“脚击”。
We can simply understand the kinetic energy using the example of a cyclist who uses the chemical energy provided by the food he consumes to accelerate a bicycle to a required speed. Thereafter, the cyclist needs to maintain this energy level without doing any further work (other than the energy required to overcome air resistance and friction).
什么是温度?
温度是物质的热能。该术语可以解释该系统的物理数量,以表达该系统的冷热性质。它是与另一个比自身更热或冷的物体接触时发生的物体热和流动的来源。温度的常见符号是“ t”,用于测量温度的SI单元是K(kelvin)。
We can measure the temperature using a thermometer. Usually, a thermometer is calibrated using different temperature scales with various different reference points. The most common scale for temperature measurement is the Celsius scale, and there are other scales such as the Fahrenheit scale and the Kelvin scale.
从理论上讲,对象或系统的最低温度值称为绝对零。到那时,我们不能从人体中提取更多的热能。在实验状态下,我们无法接近此温度值,但是我们可以接近这一点。
通常,温度是在物理,化学,地球科学,天文学,生物学,生物学,材料科学,冶金,机械工程和地理等自然科学领域进行研究的重要特性。
我们可以将温度描述为材料状态的质量,与我们用来测量其测量的任何特定温度尺度相比,我们可以将该属性命名为更抽象的实体。一些作家倾向于将其称为热情。
What is the Relationship Between Kinetic Energy and Temperature?
动能与施加的温度成正比。当系统的温度升高时,该系统中分子的振动和碰撞会增加。因此,动能增加。
动能和温度有什么区别?
动能和温度是物理化学中的两个相关术语。由于温度升高时颗粒的运动增加,因此温度的升高会增加动能。动能和温度之间的关键区别在于,动能是指移动物体的特性,是从其静止状态加速身体所需的工作,而温度是所有物质中存在的热能。
下表总结了动能和温度之间的差异。
摘要 - 动能与温度
动能和温度是物理化学中的两个相关术语。由于温度升高时颗粒的运动增加,因此温度的升高会增加动能。这key difference between kinetic energy and temperature is that kinetic energy refers to the property of a moving object where it is the work needed to accelerate a body from its resting state, whereas temperature is the thermal energy present in all matter.
