Calculate work done in a spring using Hooke's Law: Work done (W) = 0.5 k x^2, where k is the spring constant and x is the displacement from its equilibrium position. This formula helps in understanding the energy stored or expended when compressing or stretching a spring.

FAQs & Answers

  1. What is Hooke's Law? Hooke's Law states that the force needed to extend or compress a spring is directly proportional to the distance it is stretched or compressed from its original position, represented by the formula F = kx, where k is the spring constant and x is the displacement.
  2. How can I calculate the work done in compressing a spring? To calculate the work done in compressing a spring, use the formula W = 0.5 * k * x^2, where W is the work done, k is the spring constant, and x is the displacement from the equilibrium position.
  3. What units are used to measure spring constant (k)? The spring constant (k) is measured in Newtons per meter (N/m), which quantifies the stiffness of the spring.
  4. What is the significance of work done in a spring? The work done in a spring represents the energy stored when the spring is compressed or stretched, which can be released for various applications, such as in mechanical systems or in toys.
