528 views

The formula for calculating the work done by a spring is W = ½ k x². Here, W represents the work done, k is the spring constant, and x is the displacement from the equilibrium position. This formula helps in determining the energy stored or released by the spring during compression or extension.**

FAQs & Answers

  1. What does the symbol 'W' represent in the spring work formula? In the formula W = ½ k x², 'W' represents the work done by the spring, which is the energy transferred when the spring is compressed or extended.
  2. What is the spring constant 'k'? The spring constant 'k' is a measure of the stiffness of the spring. It quantifies how much force is needed to change the spring's length by a unit amount.
  3. How do you determine the displacement 'x' in the spring work formula? Displacement 'x' refers to how far the spring is stretched or compressed from its natural equilibrium position. It is measured in meters.
  4. Can the formula for work done on springs be applied to any type of spring? The formula W = ½ k x² is applicable to ideal springs that obey Hooke's Law, meaning their displacement is directly proportional to the force applied.
