The energy change is given by __________(a) ΔE=\(\frac{T^2}{S^2}\)(b)

1.	The energy change is given by __________(a) ΔE=\(\frac{T^2}{S^2}\)(b) ΔE=\(\frac{T^2}{S}\)(c) ΔE=\(\frac{T}{S}\)(d) ΔE=T x SThis question was posed to me in unit test.My enquiry is from Estimation of Take-off Distances in division Take-off and Landing Performance of Aircraft Performance
Answer» Right choice is (c) ΔE=\(\frac{T}{S}\) For explanation I WOULD SAY: The energy change is given by ΔE=excess thrust x distance MOVED i.e. ΔE=T x S where T is excess thrust and S is distance moved. This energy CHANCE happens when the AIRCRAFT is undergoing an airborne phase.
