The total amount of (net) work done by gravity as a satellite makes a complete orbit is zero. The time period of satellite does not depend on the radius of the orbit. Orbital Velocity is expressed in meter per second (m/s). suppose m is mass of the satellite then centripetal force Fc = mv²/ (h+Re) , now this force is balanced by gravitational force, You know gravitational force Fg = GMem/ (h+Re)². now equate this two force Fc = Fg. The orbital velocity of a satellite increases with the radius of the orbit II. Q.4. Notice the similarity in the equations for [latex]{v}_{\text{orbit}}[/latex] and [latex]{v}_{\text{esc}}[/latex]. The escape velocity from the Earth is about 11.3 kilometers (7 miles) per second. Orbital velocity of an artificial satellite does not depend upon (1) Mass of the earth (2) Mass of the satellite (3) Radius of the earth (4) Acceleration due to gravity If the distance between the earth and the sun were half its present value, the number of day in a year would have been. 3. The orbital velocity of a satellite increase with the radius of the orbit. A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it. Reason : Orbital velocity of a satellite, become independent of height of near satellite. The geocentric-equatorial coordinate system is used for earth-orbiting satellites. At an altitude of 124 miles (200 kilometers), the required orbital velocity is a little more than 17,000 mph (about 27,400 kph). Escape velocity depends on the mass of the planet. View Answer. 4.

With these given values the orbital period is Torbit = 5312.5s = 1.4757h (b) To calculate the orbital velocity either of the equations v = r . This "half the difference" trend breaks down when the two masses become closer to equal. Orbital velocity of the satellite, v=√ (GM e)/ (R e +h) Around the earth the value of orbital velocity is 7.92 km/sec . 3. Io, a satellite of Jupiter, has an orbital period of 1.77 days and an orbital radius of 4.22 X 105 km. Yes. The velocity is along the path and it makes an angle . C. The time period of a satellite does not depend on the radius of the orbit. (a) The minimum velocity that should be given to a satellite to orbit quite close to the earth is about 8 km/sec. 129. Which of the statement(s) given above is/are correct? The orbital speed of a satellite does not depend on its mass. Kepler's third law gives the period of a satellite in orbit around Jupiter as. A body is projected vertically from the surface of the earth of radius R with velocity equal to half of the escape velocity. The value of g, the escape velocity, and orbital velocity depend only upon the distance from the center of the planet, and not upon the mass of the object being acted upon. . At orbital velocity, Earth's or any celestial body's gravitational force pulling a moon towards its center (where all its mass lies) emulates the tension you exert on one end of a string that causes a stone attached to the other end to swing in circles around you: it becomes the centripetal force that drives a moon or satellite around it. The planet mass : The orbital velocity of a satellite is directly proportional to square root of the mass of the planet at constant radius of the orbit . CONCEPT: Orbital Velocity of Satellite: Satellites are natural or artificial bodies describing an orbit around a planet under its gravitational attraction. Answer (1 of 2): Orbital mechanics, which is the solution to Newton's law of gravitation. Venus. 2. This escape velocity √2Rg is estimated to be 11.2 km/s on the earth. Planet. False f. By definition, a geosynchronous satellite orbits the earth in a perfect circle, maintaining the There are many special cases and simplifications. Escape velocity of a particle from the surface of the earth depends on the speed with which it is fired. Since the gravitational force is only in the radial direction, it can change only . . When the radius of the orbit is 4 times than that of earth's radius, then orbital velocity in that orbit is [EAMCET (Engg.) 2. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull.Sep 27, 2017. Greater is the height of the satellite, smaller is the orbital velocity. Therefore . Due to the inertia of the moving body, the body has a tendency to move on in a straight line. Name one geostationary satellite of earth. Orbital velocity. The orbital velocity of the satellite depends on its altitude above Earth. What are the requirements of a geostationary satellite for its orbital motion. Escape velocity of a particle from the surface of the earth depends on the speed with which it is fired III. A small triangular area . This is because the orbital speed equation does not depend on the mass of the object in orbit, . The orbital velocity is inversely proportional to the square root of the radius of the orbit. (а) G is not equal to 6.67 × 10-11 Nm² kg-2 on the surface of Earth. 5. According to Kepler, the orbital period of a planet is directly proportional to the. Note: Mass of the orbiting body (Satellite) does not affect the orbital velocity. Orbital velocity of earth's satellite near the surface is 7 km/s. 2. If a satellite orbits from the north pole (geographic, not magnetic) to the south pole, its inclination is 90 degrees. Expression for orbital velocity Consider a satellite of mass m revolving with orbital velocity 'v' around the earth at a height ' h' from the surface of earth. and the altitude of the satellite above Jupiter's surface should be. Earth. The maximum orbital velocity of a satellite orbiting near its surface is For the satellite to escape gravitational pull the velocity must become v. But = 1.414 v o = (1 + 0.414) v o This means that it has to increases 0.414 in 1 or 41.4% ∴ The minimum increase required, as the velocity of satellite is maximum When it is near the earth. . The value of g depends on the latitude which is different at different locations on earth. Orbital velocity is the speed needed to stay in orbit. B.) and not ; hence, the angular momentum must remain constant. Kepler's 3rd Law of Planetary Motion says that T^2 = (4*pi^2*r^3)/(GM) T is the period of the orbit. 64.5. Orbital velocity depends upon height of satellite It is given by v= square root of (ghR) where h is the height of satellite and R is the radius of earth Critical velocity is a constant value and its value on earth is 7.9km/s It does not depends upon altitude It gives the velocity of smallest possible orbit given that there is no air friction . A The mass of the earth. Notice that we did not need to know the mass of the satellite to find the answer. 730. (b) The height of a communication satellite is about 36000 km from the earth's surface (c) The orbital velocity of the satellite depends upon the mass of the satellite The acceleration of body does not depend on the mass of falling body. If g is the acceleration due to gravity on the surface of the earth, the orbital speed of the satellite is The value of g, the escape velocity, and orbital velocity depend only upon the distance from the center of the planet, and not upon the mass of the object being acted upon. The terms (4*pi^2)/G from that equation are constants. 47.9 km/s. What is orbital velocity Class 11? The required radius of the circular orbit is therefore. At an altitude of 124 miles (200 kilometers), the required orbital velocity is a little more than 17,000 mph (about 27,400 kph). Let M be the mass of earth and R be radius of earth. (b) The escape velocity on the surface of Earth is greater than the escape velocity from moon's surface as moon has no atmosphere but Earth has. Hence the satellite will revolve around the earth in an elliptical orbit. B. If the second object were the same mass as the Earth, this trend says the speed would be half of the tiny satellite, but it turns out the speed is $\sqrt{1/2}$ or 70.7% . Greater is the height of the satellite, smaller is the orbital velocity. Notice that the orbital speed v (and therefore, the orbital period P) does not depend on the mass of the . The fundamental plane is the earth's equatorial plane and the principle axis, , points in the vernal equinox direction, .. The orbital velocity of a satellite increases with the radius of the orbit. The time period of satellite does not depend on the radius of the orbit. 1 Choose the factor on which the orbital velocity does not depend when the satellite is orbiting close to the earth's surface. No. 74 43. For the earth, Artificial satellite:- 1.The time to complete one revolution around the planet depends upon the height of the orbit. Solution: Given: R = 6.5 × 10 6 m Orbital velocity is the velocity with which satellite moves in the orbit, Due to centripetal force satellite moves in a circular path. The escape velocity is exactly 2 2 times greater, about 40% SOLUTION. The orbit, it is imperative to remember, is not a . The time period of a satellite is the ratio of the total distance travelled by the satellite around the earth to the orbital velocity. For small satellites and large planets, we can. The radial velocity of an Earth satellite is its velocity. The escape velocity is exactly 2 2 times greater, about 40% Q.3. orbital velocity of an artificial satellite does not depend upon ... (a) mass of Earth (b) mass of satellite (c) radius of Earth asked Sep 15, 2020 in Gravitation by Ruksar02 ( 52.5k points) That does not depend upon mass for the same reason the speed, at any time, of a falling object does not depend upon mass- the gravitational force is a multiple of mass so it cancels out of "F= ma". The orbital velocity of the satellite depends on its altitude above Earth. An "orbit" is just like falling with enough side-ways velocity that you keep "missing" the earth. These equations describe how the position of massive objects under the influence of gravity change with time. (v) The orbital velocity of the satellite depends on its altitude above Earth. Now consider . The moon having 1.23% of Earth's mass would move 0.61% slower than a tiny satellite.
