Why doesn't the force of gravity change t he speed of a satellite in a circluar orbit?
Two answers:
Answer #1:
How do you know that it doesn't ?
Answer #2:
Because that's the way gravity works. If you take Newton's simple formula for
the force of gravity, and you have enough geometry and calculus to work with,
you can massage the gravity formula around and discover many facts about
orbits, including these:
-- Every closed orbit is an ellipse.
-- The period of a closed orbit only depends on the dimensions of the ellipse,
not on the mass of the minor body.
(Lucky for an astronaut in the middle of a "space walk" ... it means he can stay in
the same earth-orbit as the Space Shuttle even when he's not holding on to it.)
-- If the orbit isn't circular and the distance between the two bodies changes during
the orbit, then the speed of the minor body is greatest when they're closest together,
and lowest when they're farthest apart.
-- Every open orbit is a hyperbola.

When is the force of gravity the greatest on you?
doesnt matter what time it is. gravity always has the same force over you unless your on a different planet.
When you jump why does gravity pull you back down?
Gravity is the force that pulls objects toward each other. When you jump, you initially overcome gravity's force with the momentum from your leg muscles. However, as you move away from the ground, gravity starts pulling you back down until you land again.
How do objects acquire potential energy?
For an object to require potential energy a force must be acting on it in a certain direction. Even though the object doesnt move doesnt mean it has potential energy. The most common force of otential energy is Gravity. When an object is lifted off the ground gravity becomes stronger. For a formula of proof then use E=FxD (Energy=Force applied x Distance travelled). If a ball has been lifted by 10 Meters with a force of 500 Newtons then it has a Potential Energy of 5000 Newton Meters,
When did newton come up with gravity?
Sir Isaac Newton formulated his theory of gravity in 1687, with the publication of his groundbreaking work, "Principia Mathematica." This theory described the force of gravity as a universal force of attraction between all objects possessing mass.
How does your distance from plants affect your gravity?
Your distance from plants does not affect gravity. Gravity is a force of attraction between objects with mass, such as the Earth and everything on it. Plants do not have a significant influence on the force of gravity acting on you based on how close you are to them.
What is the second greatest source of gravity in space?
Gravity doesnt have a source.
Does gravity attract everything together?
No Magnetism As Weel Wich dOESNT iNCLUDE gRAVITY :)
Why doesnt a geostationary satellite trace a path over the surface of the earth?
A geostationary satellite does not trace a path over the surface of the earth because that is what geostationary means - the satellite is stationary over a point on the Earth.
What are the changes of the earth when its gravity is as weak as the moon?
Gravity doesnt decline like magnetism, its fixed and proportional to the mass of the earth.
How does a frog change in spring?
it doesnt change
Is there a possibility that gravity doesnt exist?
No. Gravity exists. You have proof of this fact by the way you are held down when you walk instead of floating around.
How could plants develop in a zero-gravity environment?
They cant, if the did they planet would fall apart, zero-gravity doesnt exist.
Why doesnt the force of gravity pull the moon into earth?
because of the power of bacon
How did the Hunger Games change?
it doesnt change you dumb
Does the gravity t have signature on it?
No i have the same phone and I looked very hard to find it, but it doesnt have it.
What is the next step if gravity bleed doesnt fix the problem?
Need to know what the problem is.
Why does your scrotum change color?
it doesnt.
