Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth. At the correct orbital velocity, ...
or, the total vector force on an object is equation to the time-rate of change of its vector momentum. basically, forces change the momentum of an object. in this case, we can say that the vector momentum is the product of mass and vector velocity. the last thing is the change in ...
What you are asking about is how to convert from one set of six numbers, three position coordinates and three velocity components (note that simply direction is not sufficient), to another set of six numbers, the six orbital elements. I'm not going to give you the equations, but I'll g...
Galaxies are large systems of stars, gas, dust and dark matter that orbits a center and is bound by gravity. Learn about the characteristics of galaxies.
Also Read:What Is Orbital Velocity? Using Geometry Another way to guess the mass of the planet is by applying principles of geometry. However, this involves more calculative guessing than the actual measurement. If you can calculate the volume of the planet and make a rough estimate about the...
We also find some special characteristics for each routine. If the system went through pairwise 2:1 MMRs at the beginning, the MMR of the outer two planets would be broken first to reach the current state. As for routine (iii), the planets would be out of the LR at the place where...
Recall that orbital velocities/speeds depend on the mass of the host star only: v = √(GM/r) where G is the gravitational constant, M is the mass, and r is the orbital radius. (a) Solve this for radius, substitute their speeds respectively, and take the ratio of the two radii for...
Higher is slower - orbit radius is inversely proportional to orbital velocity. So if you are "ahead" of your target and want it to catch up, you should go into a higher orbit (one with a longer period) and hang out there for a while, and come back. If you need to catch up your...
How to Find the Period of an Element? The value of n for the outermost or valence shell is shown by the period. The number of shells in an atom determines the period. The period of an element is represented by the principal quantum number (n) of the valence electrons in the electronic...
Hi. I am working on a research paper for my high school and I am trying to calculate the mass of an exoplanet using the radial velocity values of its star. However, I am confused as to the binary mass function and what units you would use. I also wanted to know how you would inte...
