Elastic Potential Energy

弹性势能
Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched. According to Hooke's law, the force required to stretch the spring will be directly proportional to the amount of stretch.

Since the force has the form

由于力的形式

F = -kx

F = -kx(专名或术语)

then the work done to stretch the spring a distance x is

然后将弹簧拉伸距离x所做的功是

For spring constant k=N/m
and displacement x =m,
the potential energy = J.
对于弹簧常数 k = N/m 和位移 x = m,势能 = J。

Spring Potential Energy

弹簧势能
Since the change in Potential energy of an object between two positions is equal to the work that must be done to move the object from one point to the other, the calculation of potential energy is equivalent to calculating the work. Since the force required to stretch a spring changes with distance, the calculation of the work involves an integral.

The work can also be visualized as the area under the force curve:

功也可以被可视化为力曲线下的面积:

由于物体在两个位置之间的势能变化等于将物体从一个点移动到另一个点所必须做的功,因此计算势能等同于计算功。由于拉伸弹簧所需的力随距离变化,因此计算功涉及一个积分。
