The text in the first frame are not much visible. Sir you could have given with a bigger fonts. wow, it is extremely interesting to visualise the path of the earth motion (with the video) I understand that although the earth motion shape is the same but the path is not the same. this lesson is quite interesting and made me to comprehend the concept very well.
An elliptical orbit, also called an eccentric orbit, is in the shape of an ellipse. In an elliptical orbit, the satellite's velocity changes depending on where it is in its orbital path.
polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution.
All satellites are launched to space and into their orbit by hitching a ride on a rocket or on the Space Shuttle, where they are placed inside the cargo bay. ... This allows the rocket to penetrate the densest layer of the Earth's atmosphere quickly, which helps reduce fuel consumption.
An object in motion will stay in motion unless something pushes or pulls on it. This statement is called Newton's first law of motion. Without gravity, an Earth-orbiting satellite would go off into space along a straight line. With gravity, it is pulled back toward Earth.
Most satellites are launched into space on rockets. A satellite orbits Earth when its speed is balanced by the pull of Earth's gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth.
An orbit is the result of a perfect balance between gravity pulling a satellite down and the satellite going forward. A satellite that is going very fast will keep going forward very fast, because of inertia.
Polar orbits are used for reconnaissance and Earth observation. If a satellite is in polar orbit at an altitude of 800 km, it will be travelling at a speed of approximately 7.5 km per second.
Gravity is a force that attracts all objects towards each other. People are attracted towards the Earth and the Earth towards people, the Moon and the Earth are attracted towards each other, and the Sun and the Earth are attracted towards each other.
There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. ... The higher a satellite's orbit, the slower it moves.

Polar Satellite Launch Vehicle. The Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV, is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO). ... PSLV can also launch small size satellites into geostationary transfer orbit (GTO).
The Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV, is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun-synchronous orbits.
Satellites orbit Earth at different heights, different speeds and along different paths. The two most common types of orbit are "geostationary" (jee-oh-STAY-shun-air-ee) and "polar." A geostationary satellite travels from west to east over the equator.
Image result for how many satellites are orbiting the earth?www.youtube.com This definition makes our count much less because it includes only spacecraft and not debris that orbits the Earth. The Goddard Space Flight Center's lists 2,271 satellites currently in orbit.
The object is now in free fall. Replace the object you shot away by a spaceship and the tall structure by a rocket and you get the picture: a spaceship in orbit around earth is in free fall.
Satellites—that is, artificial satellites, as opposed to natural satellites like the moon—are carried into space by rockets. ... The Earth is curving away while both the rocket and the satellite “fall” around the Earth.

DeleteWhat keeps satellites in orbit?
ReplyDeleteGravity is important to keep satellites in orbit. Well, I guess not just important, it's crucial – it's what keeps the satellite in orbit.
