PHY 2048 Lecture Notes - Lecture 13: Centripetal Force, Miele, Ford Sigma Engine
Document Summary
Any particle in the universe attracts every other particle with a force givenby. Fg g mi mz r z r i s nk. Fg magnitude of gravitational force between m and m r distance between two particles. 6. 67 10 i ex m 50 kg mz. 50 100 z 2 weight weight gravitational force on the object by the earth. Fez up from the surface g decreases down from the surface g also decreases surface would be max g value i ex notion of satellite. L r m to 0t ni i i i n any objectmoving in a circle is kept in that circle by centripetal force m mass of satellite r distance of satellite fromearth radius of satellite"s orbit. The centripetal force on the satellite in given orbit is. Mv 2 r re me i i v. Gravitational force between satellite and earth provides the centripetal force for the motion.
