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 ...

WebbThe actual equation should be 1/2 kx 2 + 1/2 mv 2 = E, where E is the total energy and therefore constant. Both "calculate the energy" but Hooke's law is potential energy and …
Webb7 jan. 2013 · We were supposed to graph the height and speed, and I ended up with something resembling a square root graph. We were required to linearize the data (so that we could have a single slope), so I squared the heights and got a slope of about $-0.11\,cm^{-1}\,s^{-1}$: I don't understand what the slope is supposed to signify. 口コミ 下呂温泉WebbClick here👆to get an answer to your question ️ Check the dimensional correctness of relation: mgh=1/2 mv, where letters have their usual meanings.
