Work done on a spring refers to the energy transferred to the spring when it is either compressed or stretched from its equilibrium position. This energy is stored as potential energy in the spring, and it relates directly to Hooke's law, which states that the force exerted by a spring is proportional to the displacement from its rest position. The work done can be calculated using the formula $$W = \frac{1}{2} k x^2$$, where \(W\) is the work done, \(k\) is the spring constant, and \(x\) is the displacement from the equilibrium position.
congrats on reading the definition of work done on a spring. now let's actually learn it.
