When an object is orbit around a planet, what is it actually going on?The force of Earth's gravity pushes outward and keeps the object from falling.Gravity, combined with the satellite's momentum, cause the satellite to stay orbit above Earth, instead offalling back down to the ground. These forces must be in balance to maintain an orbit.The object starts to have no mass, and therefore can stay in orbit.When the object is in orbit, gravity no longer acts upon that object, and therefore can maintain its constantcircular path without a influence of an outside force.

A 3500-kg spaceship is in a circular orbit 220 km above the surface of Earth. It needs to be moved into a higher circular orbit of 390 km to link up with the space station at that altitude. In this problem you can take the mass of the Earth to be 5.97 × 1024 kg.How much work, in joules, do the spaceship’s engines have to perform to move to the higher orbit? Ignore any change of mass due to fuel consumption.

A satellite is in a circular orbit of radius r around the Earth. (Use the following as necessary: G, ME, and r.) a) Determine an expression that will allow you to find the speed of the satellite. b)The satellite splits into two fragments, with masses m and 4m. The fragment with mass m is initially at rest with respect to the Earth, then falls straight towards the Earth. The fragment with mass 4m moves with initial speed vi. Find an expression for vi. c)Because of the increase in its speed, this larger fragment now moves in an elliptical orbit. Find an expression for the fragment's distance away from the center of the Earth when it reaches the far end of the ellipse.
The Earth may be assumed to be an isolated uniform sphere with its mass of 6.0 x 1024 kg concentrated at its centre. A satellite of mass 1200kg is in a circular orbit about the Earth in the Earth's gravitational field. The period of the orbit is 94 minutes. (c) Rockets on the satellite are fired so that the satellite enters a different circular orbit that has a period of 150 minutes. The change in the mass of the satellite may be assumed to be negligible. (i) Show that the radius of the new orbit is 9.4 x 106 m. (ii) State, with a reason, whether the gravitational potential energy of the satellite increases or decreases. 3 (iii) Determine the magnitude of the change in the gravitational potential energy of the satellite.
Consider a system that is comprised of two planets. These two planets orbit each other, both following stable circular orbits about the center of mass. Assume that they are so distant from other bodies in the universe that any forces from other bodies are negligible. Which of the statements below about the system comprising of these two planets are correct? The planets will get increasingly closer to each other due to the attractive gravitational force between them. As there are no non-conservative forces doing work on this system, the mechanical energy (kinetic plus potential energy) is conserved. When considering this system, the force of one planet on the other is an external force. The acceleration of the center of mass of the two planet system is zero.

White dwarf stars are produced by the collapse of regular stars, such as our sun, toward the end of their normal life. Suppose a star initially has the same mass as our sun and the same radius as that of the sun. Suppose further that it collapses into a white dwarf with a radius of 5000km. If the initial period of the star is the same 27 day period of our sun, what is the resulting period of the white dwarf?
