WebTranscribed Image Text: The gravitational force of a star on orbiting planet 1 is F₁. Planet 2, which is twice as massive as planet 1 and orbits at twice the distance from the star, experiences gravitational force F₂. Part A What is the ratio F12 F₂. WebThere is no net external force or torque acting on the Sun-planet system, and the only force is gravity between the Sun and planet. Therefore, angular momentum and energy remain constant. However, the gravitational potential energy does change, because it depends on … blockchain full course free download
