Document Summary
Myhre ( newton "s law of gravitation ) Principle of superposition - a net effect is the sum of the individual effects : first compute the individual gravitational forces that act on our particle due to each of. We then find the net force by adding these forces done when adding forces in earlier chapters . the other particles vector i ally , selected as we have: net. Example: net gravitational force, 2d, three particles y. What is the net gravitational force f. net on particle 1 due to the other particles ? fine , , y , f . M = mass of earth r m - Wr ) measured = magnitude of gravitational weight force. Example: difference in acceleration at head and feet (a) an astronaut whose height h is 1. 70 m floats feet down in an orbiting space shuttle at distance r. 6. 77 106 m away from the center of earth .
