Orbital Velocity is the velocity at which a body revolves around another body. It is an important concept in the field of astronomy and physics. It is used extensively to launch satellites into orbits and to make sure that they stay in their orbits.
The orbital speed of the earth around the sun is 108,000 km per hour. It is relating the mass of a given planet to the gravitational constant and radius through the formula given. The orbital speed formula contains a constant, G, known as the “universal gravitational constant”. Its value is \ (6.673 \times 10^ {-11} N m^2 kg^ {-2}\).
The orbital velocity v of a satellite may depend on its mass m, the distance r from the centre of the earth and acceleration due to gravity g. Obtain an expression for its orbital velocity. (Ans. v = k/rg) 13.
Solution. Verified by Toppr. Orbital velocity is the velocity at which a body revolves around the other body. Objects that travel in uniform circular motion around the Earth are called to be in orbit. The velocity of this orbit depends on the distance between the object and the center of the earth.
The orbital velocity of an artificial satellite in a circular orbit of a height R above earth's surface is v (R is radius of earth). The orbit velocity of a satellite orbiting at an altitude 2 R above the earth's surface will be:
The orbital velocity of an artificial satellite in a circular orbit of a height R above earth's surface is v (R is radius of earth). The orbit velocity of a satellite orbiting at an altitude 2 R above the earth's surface will be:
A satellite of mass 'm' is revolving in circular orbit of radius 'r' round the earth. Its angular momentum w.r.t. the centre of its orbit is (M = mass of earth, G = universal gravitational constant)
A planet is revolving round the sun in an elliptical orbit, if v is the velocity of the planet when its position vector from the sun is r, then areal velocity of the planet is a) I v x r I b) 2 I r x v I c) I 1/2(r x v) I d) None of these
The orbital velocity of an artificial satellite in a circular orbit just above the earth's surface is v.For a satellite orbiting at an altitude of half the earth's radius, the orbital velocity will be
43) If v 0 be the orbital velocity of an artificial satellite orbiting just above the earth's surface, then the orbital velocity of the same satellite orbiting at an altitude equal to earth's radius is.
