Unformatted text preview: Physics 1 Discussion Section Problem for the week of April 19-23, 2010 Instructions: Work this problem as a group. Hand in only one completed work- sheet for your group, including all of the steps in the I SEE problem-solving process. Problem: The Orbits of the Planets The table below lists the average distance from each planet to the Sun and the time each planet takes to make a complete orbit around the Sun (Orbital period). The orbits of all of the planets are roughly circular. Your job is to determine a relationship between the radius r of a planets orbit (in meters) and the centripetal acceleration a rad of the planet (in m/s 2 ). In particular, you are to see whether these two quantities can be related by an equation of the form a rad = Cr n , where C and n are constants. You are then to determine the values of C and n . Based on your results, determine whether the acceleration of the planets in- creases, decreases, or stays the same as the Sun-planet distance increases, and dis-...
