For example, students readily recognize that ideas they acquire from the observation of objects in everyday life. If the mass is moving too slowly to maintain its circular motion, it will fail to complete the loop. 2 Identify an equation that can be used to analyze physical situation. The speed of the spacecraft in the second orbit will be slower because in the equation \(G\frac{mM_{E}}{r^{2}} = \frac{mv^{2}}{r}\) , the ms and rs cancel and you get the equation \(\frac{GM_{E}}{r} =v ^{2}\) .
