Question
The total energy of an orbiting satellite in uniform circular motion is negative because of the magnitude of U, which is also negative. Consider the equation U = -GmMelr. Which of the following is not correct? if r2 Is greater than r1 aid an object moves from r1to r2, then the gravitational potent al energy Increases. The potential energy of a satellite increases as it moves away from the Earth. The potential energy, U, is zero when the mass is infinitely far away from the Earth (r = infinity). You can assume that U equal zero at some arbitrary point (e.g., at the surface of the Earth).Explanation / Answer
first option is false if r_1> r_2 --> 1/r_1 < 1/r_2 ---> U_1 > U_2 Hence potnetial energy decreases as you move from r1 to r2, not increases.Related Questions
