Lab 05: VPython Curving motion in an orbit (Lab) BRANDON JARROTT FELDKAMP PHYS 2211, section M, Fall 2008 Instructor: Jennifer Curtis Web Assign Current Score: 30 out of 30 Due: Monday, September 29, 2008 09:00 AM EDT Description Modify your orbit program from Lab 3 to include the parallel and perpendicular components of the rate of change of momentum. Instructions When you turn in your program, WebAssign will display full credit, but there may be deductions later when a grader inspects your work. The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. 8/8 points Curving motion in the computer model of an orbit: Follow the instructions on the handout on the course website for modifying your orbit program to calculate and display the tangential and perpendicular components of the rate of change of momentum. Then, answer the questions below. (a) Where in the Earth's orbit is the tangential component of the net force in the same direction as the Earth's momentum? Along the part of the path where the Earth is moving toward the Sun At the point where the Earth is farthest from the Sun Along the part of the path where the Earth is moving away from the Sun At the point where the Earth is closest to the Sun (b) When the tangential component of the net force is in the same direction as the momentum, what is happening to the speed (magnitude of velocity) of the Earth? The Earth's speed is increasing.
