ke2
|
|
|
1/2 k e2
|
|
|
2 k e2
|
Explanation:
Detailed explanation-1: -The slight preference for 1/2 kx^2 is down simply to the fact that you need only measure one variable-the dispalcement x inorder to find the stored energy. If you use 1/2 F/x then you have to measure displacement and force-very often the force is not easy to measure.
Detailed explanation-2: -The Elastic Potential Energy Calculator uses the formula U = ½kx² where U is the elastic energy, k is the spring constant and x is the change in position or displacement, such as the distance a spring is being stretched.
