Satellites and how they work?

Question

i would just a like a small paragraph explaining how Satellites work in general if that is possible please.

Thank you

Answer 1

I've broken down my answer to make it easier to digest.  I hope that's okay.

(1) Centrifugal force is a fictitious force.  There isn't really any force pushing outward against satellites.

(2) A satellite is any body that orbits something else.  Technically, the Earth is a satellite of the Sun, but for the purposes of this discussion, I'll assume you mean specifically satellites that orbit the Earth.

(3) There are natural satellites and artificial satellites.  The Moon is a natural satellite of the Earth.  The Hubble Space Telescope and the International Space Station are artificial satellites.

(4) Satellites stay in orbit because of inertia and gravity.

(5)  A satellite "wants" to keep moving in a straight line (Newton's first law) and it would do so if it weren't influenced by an outside force.

(6) Gravity pulls on the satellite, causing its path to bend toward the Earth.  With the right combination of gravity and speed, you can put a satellite in an elliptical path that never intersects the Earth.  This path is called an orbit.

(7) Orbits can change over time due to outside influences.  For example, the Moon's gravity can cause a satellite's orbit to change; so can being pelted by micrometeroids.  Some satellites that orbit very close to the Earth actually pass through the uppermost layers of Earth's atmosphere.  Although the air is VERY thin, it drags on the satellite and causes them to slow down a bit.  This changes the satellite's orbit as well.

(8) In order to correct the satellites' orbits, many of them have small rocket motors that periodically fire to push them back into the proper orbit.

(9) Artificial satellites can be placed into different orbits depending on what they do.  TV signal satellites are often placed into geostationary orbits, meaning that they take exactly 24 hours to orbit the Earth and appear to remain motionless in the sky.  They aren't really motionless, of course; it's just that the Earth is rotating at the same rate beneath these satellites.  Reconnaissance satellites often have inclined orbits that allow them to sweep over large portions of the globe as it rotates beneath them.

I know that's a bit more than a short paragraph.  If you need this for a school assignment, maybe you can select a few key pieces of information to re-write in your own words.  I hope that helps.  Good luck!

Answer 2

satellites are of two types natural and artificial like moon is an natural satellite but sattelitse that bring to you programs or matches of sports are artificial satellites they also revolve around the earth like bearth revolves around the sun I hope understanded

Answer 3

Artificial satellites? They recieve and transmit signals while orbiting the Earth!

Answer 4

its all about gravity and centrifugal force. gravity from the earth tries to pull the satellites to the earth, but because they are spinning around the earth, that gives them centrifugal force in the opposite direction, making them stay up. (like if you spin a bucket full of water around it doesnt spill out if you spin it fast enough)

best i can do.

make it a good day
