To calculate work with a spring, use the formula W = (1/2) k x², where W is the work done, k is the spring constant, and x is the displacement from the spring's equilibrium position. This equation captures the energy stored or released by the spring.

FAQs & Answers

  1. What is the formula for calculating work done by a spring? The formula for calculating work done by a spring is W = (1/2) k x², where W is the work, k is the spring constant, and x is the displacement from the spring's equilibrium position.
  2. What do the variables in the work formula represent? In the formula W = (1/2) k x², W represents the work done, k is the spring constant which indicates how stiff the spring is, and x is the distance the spring is compressed or stretched from its rest position.
  3. How does the spring constant affect the work done? The spring constant (k) directly affects the amount of work done. A higher spring constant indicates a stiffer spring and results in more work being done for the same displacement.
  4. What units are used in calculating work with springs? The work done with springs is typically measured in joules (J), where the spring constant (k) is measured in newtons per meter (N/m), and displacement (x) is measured in meters (m).
