Step by Step Calculation

Back to Top
Step 1 :  

Elastic Potential Energy Formula:

Spring Potential Energy:U = (1/2)*(k)*(x)2
Spring Force Constant:k = 2U/(x)2
Spring Stretch Length:x = square root of(2U/k)
Where,
U = Spring Potential Energy,
k = Spring Force Constant,
x = Spring Stretch Length.



Step 2 :  

State the equation you plan to use and plug in the values.



Example Problems

  1. A compressed spring that obeys Hooke's law has a spring constant of 532 N/m and the distance by which the spring is compressed is 0.33m, then calculate the potential energy of the spring?


    Step 1 :  

    Given that:
    Spring Force Constant(k) = 532 N/m
    Spring Stretch Length(x) = 0.33m
    Spring Potential Energy(U) = ? 


     



    Step 2 :  

    Substitue the given values in the formula:
    Spring Potential Energy:U = (1/2)*(k)*(x)2
    U = (1/2)*(532)*(0.33)2
    U = 28.967 J



    Answer  :  

    U = 28.967 J



  2. A spring has a force constant of 400 N/m. How far must it be stretched for it's potential energy to be 28J?


    Step 1 :  

    Given that:
    Spring Force Constant(k) = 400 N/m
    Spring Potential Energy(U) = 28J
    Spring Stretch Length(x) = ?


     



    Step 2 :  

    Substitue the given values in the formula:
    Spring Stretch Length:x = square root of(2U/k)
    x = square root of((2×28)/400)
    x = square root of(0.14)
    x =  0.374m



    Answer  :  

    x =  0.374m
