Detailed explanation-1: -Which of these vary for satellites in circular orbits? kinetic energy.
Detailed explanation-2: -According to Kepler, Angular momentum is conserved for a satellite in orbit.
Detailed explanation-3: -The gravitational force between the Earth and satellite is the centripetal force of the circular motion.
Detailed explanation-4: -All orbits are elliptical, which means they are an ellipse, similar to an oval. For the planets, the orbits are almost circular. The orbits of comets have a different shape. They are highly eccentric or “squashed.” They look more like thin ellipses than circles.
Detailed explanation-5: -Situations where there is circular motion and a much larger central body include: planets orbiting the Sun, moons orbiting large planets, and satellites. They both have the same velocity.
