WebbPE mgh grav In the previous chapter, we showed that the work done by an external force to stretch or compress a spring by an amount x is 1 2 W kx ext 2. We therefore have that the elastic potential energy contained in a spring is PE W elas ext or 1 2 PE kx elas 2 In writing this formula, we have set PE elas = 0 at x = 0 (the unstretched position). Webb1 − v2 c2 1/2 arises in the study of relativity. Suppose we want to rearrange it to find an expression for v c. We begin by noticing that if we square both sides this will remove the square root term (i.e. the power 1 2) on the right-hand side. So squaring: T2 = T2 0 1 − v2 c2 We remove the fraction by multiplying both sides by 1 − v2 c2 ...
