Are the moon and sun considered planets?
No. The sun is a star. The moon is a moon, also called a natural satellite, as it orbits Earth rather than the sun.
What is the moon a planet or something?
The moon is a moon, also known as a natural satellite. It is not considered a planet as it orbits a planet (Earth) rather than the sun.
In the southern hemisphere do the width of the ocean increase or decreses from the equator to the pole.?
The width of the ocean generally increases from the equator towards the poles in the southern hemisphere. This is because the Earth is not a perfect sphere, but rather an oblate spheroid, which causes the circumference to be larger near the poles than at the equator.
How is a satellite placed in orbit and why it retains its position in space?
This can vary depending on the function of the satellite. In general, the satellite is launched by unmanned rockets or from the space shuttle payload bay at the correct altitude. After the satellite is released from the launch vehicle, the speed of a satellite is adjusted so that the rate at which it is being pulled back toward the earth is the same as the rate at which the earth is turning underneath it. So it is continually falling but not hitting the earth. This is what is also happening to the space shuttle when in earth orbit and the ISS. Satellites in geostationary orbit - where they appear to remain over a single point on the earth - must have a circular orbit for this to occur. That is why they are placed over the equator. Any other orbit is elliptical in shape. The problem that arises is that the earth is not perfectly round, even at the equator, and so the orbit of geostationary satellites must be adjusted every two weeks to compensate for this. The engines are remotely fired for the correct amount of time. When the fuel runs out, this can no longer be done. Orbital mechanics is a complex and detailed concept to understand. See some of the Web Links to the left.
Why is Pluto classified as a dwarf planet rather than a satellite of Neptune?
Pluto is classified as a dwarf planet because it does not meet the criteria to be considered a full-fledged planet. Its small size, orbital characteristics, and relationship with other celestial bodies led to its reclassification in 2006. Pluto orbits the Sun directly, rather than being a satellite of Neptune.
What causes satellite to stay in orbit rather than falling towards earth?
Its forward motion. Please understand that something in orbit IS falling towards Earth.
What provides the forces that causes the centripetal acceleration of a satellite in orbit?
When something is moving in circular motion there are two forces that concern the object, excluding forces affecting the motion of the object going around the circle as these would not make the acceleration constant, the force that pushes it inwards towards the centre of circle and the force that pushes it outwards towards the circle, the gravitational field from the mass at the centre of the orbit will provide the inward force, pulling the object inwards towards the centre, and the weight of the satellite will push it outwards towards the edge of the circle Correction- there is only one force- gravity- acting on a satellite in orbit. If it weren't for gravity, the satellite would fly off in a straight line. There is no outward pushing force.
Is it correct to say that satellites stay in orbit rather than falling to Earth because they are beyond the pool of Earth's gravity?
No, satellites stay in orbit due to the balance between their forward momentum and the gravitational pull of the Earth. This balance allows them to continuously fall towards Earth while also moving forward at a speed that prevents them from getting closer. This is known as free fall or microgravity.
How motion of satellite similar to the motion of an object in freefall?
A satellite is in free fall. When the only force acting upon it is gravity, it reacts freely to this gravity, accelerating towards Earth. That is to say, instead of going in a straight line, the velocity vector changes direction, towards Earth. If the satellite is fast enough to be in orbit, it will never actually fall on Earth; but the velocity vector changes all the time.
What are 2 examples of earth's gravitational pull?
The gravitational pull of Earth keeps objects and people on the surface rather than floating off into space. The gravitational pull of Earth causes the tides in the oceans by attracting water towards the center of the planet.
How is a satellite's orbit like a falling basketball?
Because it is falling. Really. We call it "free fall" rather than "weightlessness", because things in space still have weight; it's just that when we're falling, we don't FEEL the weight. We only feel it when we are RESISTING the weight, such as standing on the Earth, or sitting or standing. Make a parachute jump, and before you open your parachute you won't be "weightless", but you WILL be in "free fall". So what's the difference between a satellite and a basketball? The ball isn't going very fast, and it will hit the ground - and bounce. A satellite is moving SIDEWAYS so fast that by the time it has fallen, the satellite has already missed the Earth. And it KEEPS moving so fast that the satellite KEEPS MISSING! This happens because there is no (or very little) air in space, so there is nothing to cause the satellite to slow down. The lowest practical orbits are about 120 miles up; much lower, and the satellite will encounter some tiny trace of air resistance, which will begin to slow the satellite down and cause it to fall to Earth. At that altitude, the orbital velocity is about 18,000 miles per hour.
What is the name of the second satellite?
The name of the second satellite can vary depending on the context. It could be any specific satellite's name, such as "Hubble Space Telescope," "GPS satellite," or "ISS (International Space Station) satellite."
A satellite is projectile that falls ot of earth rather than into earth?
Satellites are in constant free-fall. This simply means they are constantly being accelerated by earth's gravity. However, an orbiting satellite's lateral motion is sufficient that the acceleration caused by the earth's gravity causes it to continually circle the earth, instead of crashing to the ground.
What is the correct intonation for statements?
The correct intonation for statements is generally falling, where your voice goes down in pitch towards the end of the sentence. This helps indicate that you are making a statement rather than asking a question.
What is a satellite phone?
A satellite phone is a mobile phone that connect to an satellite in orbit rather than a cell tower. These types of phones are commonly used by military serving overseas because they can get a signal all over the Earth.
What role did a satellite play in the beginning of the space race?
The launch of the Soviet satellite Sputnik 1 in 1957 marked the beginning of the space race. Sputnik demonstrated Soviet technological prowess and sparked fears of potential military uses of space technology, leading to increased focus on space exploration and competition between the United States and Soviet Union.
What force causes object to change direction?
gravity (up to down) friction
