Question

    The energy stored in a stretched spring

    is:
    A 1/2 mv² Correct Answer Incorrect Answer
    B 1/2 kx² Correct Answer Incorrect Answer
    C 1/2 kx Correct Answer Incorrect Answer
    D kx Correct Answer Incorrect Answer

    Solution

    The potential energy stored in a stretched or compressed spring follows Hooke’s Law: U = 1/2 kx² Here, k is the spring constant and x is the displacement from the natural length. This energy is due to the work done in stretching or compressing the spring. So, correct expression is 1/2 kx².
