(33%) Problem 1: Material for this Lab Experiment 5 Manual General Lab Documents TOC and Introduction Appendix A: Measurements, Uncertainty and Propagation of Errors Appendix B: The Tektronix TDS 210 Digital Oscilloscope asteroid This pre-lab question is about gravitational potential energy. There are many analogies between gravitational potential and electrical potential, and this exercise is intended to help you get better intuition about electrical potential energy. The figure shows the gravitational equipotential surfaces (red curves) around a non-spherical asteroid (blue oval). The dashed red curve is where the equipotential has been chosen to be zero. The black curves show the direction the gravitational force from the asteroid is pointing 20% Part (a) If a small rock is released from rest at point A, it will start accelerating towards the asteroid due to the force of gravity. (True or False?) 20% Part (b) At which point, A or B, would the rock have more gravitational potential energy? > 20% Part (c) It takes 280 Joules of work to lift the rock of mass 0.50 kg from the dashed red curve to point A Using this information, determine the potential energy in J of the rock at the point A Grade Summary Deductions Potential PE-1 0% 100% Submissions cosO asin atan)acotanO sinhO cosh) tanh cotanh) °Degrees Radians in tan Attempts remaining: 3 (4% per attempt) detailed view cotan acosO Submit I give up !Explanation / Answer
c)True
b)B, since it is at lesser distance from the Asteroid.
c)W = 280 J
Since the gravitatioanl potential ebergy is simply the energy required to move a mass at a certain heigt.
