Why There is no work done when satellite rotate around earth?
With satellites, the object is not to escape Earth's gravity, but to balance it. Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion -- the satellite's tendency to keep going.This is approximately 17,000 mph (27,359 kph) at an altitude of 150 miles (242 km). Without gravity, the satellite's inertia would carry it off into space. Even with gravity, if the intended satellite goes too fast, it will eventually fly away. On the other hand, if the satellite goes too slowly, gravity will pull it back to Earth.At the correct orbital velocity, gravity exactly balances the satellite's inertia, pulling down toward Earth's center just enough to keep the path of the satellite curving like Earth's curved surface, rather than flying off in a straight line.
What is geothermo energy?
Thermal energy is generated and measured by heat of any kind. It is caused by the increased activity or velocity of molecules in a substance, which in turn causes temperature to rise accordingly.
A satellite in orbit around earth is always falling towards earth?
Yes. They accelerate (change the direction of their movement) towards Earth, and this may be labelled as "falling".Yes.

Why doesn't a satellite in orbit around earth slow down?
Artificial satellites are outside of the atmosphere, and therefore do not experience any friction with it. They are in the vacuum of space, where nothing will slow them down by friction. Since they have enough velocity to keep from dropping below the atmosphere of Earth, they are in a stable orbit, the same way the Moon is. However, they do not move at perfectly uniform speed. Like all satellites of all bodies, they move more speedily when they are closer to earth and less speedily when they are farther away from Earth. Their orbits can be corrected by changing their orbital velocity, but it is nearly impossible to get a perfectly circular orbit. Being in a close to circular orbit, they remain nearly uniform in velocity.
Is the satellite accelerating?
Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.
The velocity required to keed a satellite in orbit around the Earth is called?
circular velocity
Is the velocity of any satellite 0 with reference to cos theta?
velocity of any satellite revolving around any planet is 0 with reference to cos theta. the velocity in circular motion is taken in tangential direction. when the velocity of any satellite is taken tangential , then it forms 90 degrees with the radius of the Earth. we know that cos90 = 0. therefore,velocity of satellites is 0 with reference to cos theta. but this contradicts the fact that " any body with 0 velocity would collide the Earth" stated by Issac Newton. scientists are still researching to get an appropriate answer to this question. - by d.s.rahul
What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
circular.
If the mass of a statellite is doubled while the radius of its orbit remains constant then the speed of the satellite is increased by how much?
The velocity at which the satellite was launched would have to be increased in order for it to maintain the same orbit. So the speed would be increased.
Is the velocity of all the satellites zero since cos90 equals 0?
in my opinion, the velocity of any body moving in a circular path is directed in tangential direction. when the velocity is took tangential,its angle formed with reference to the earths radius is 90 degrees. we know that cos90 = 0. therefore,the velocity of the satellites revolving around the earth must be 0 with reference to cos theta. velocity of any satellite revolving around any planet is 0 with reference to cos theta. but this contradicts the fact that " any body with 0 velocity would collide the Earth" stated by Issac Newton. scientists are still researching to get an appropriate answer to this question. - by d.s.rahul
Which physical quantity is conserved of an earth satellite?
Velocity of satellite and hence its linear momentum changes continuously due to the change in the direction of motion in a circular orbit. However, angular momentum is conserved as no external torque acts on the satellite.
Why do Satellites travel in a circular path?
Satellites orbit the Earth or other bodies due to a careful balance of their velocity and the gravitational attraction of the body. Essentially gravity pulls them down but their velocity moves then out (Newton's Fist Law of Motion) at the same rate. They keep missing the body they orbit.The path is not necessarily circular since the gravity over the Earth varies with the density of the ground below the satellite. They are also satisfied to be in an elliptical orbit (closer at some times than others). The moon is a good example of a satellite in an almost circular elliptical orbit. comets have wildly elliptical orbits.
A satellite in an elliptical orbit travels at constant what?
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
How circular velocity is constant in circular motion?
Velocity constantly changes as so does the direction around a circle...
What would be the effect on the orbital velocity of satellite if mass of satellite is double?
Its mass won't affect the orbital velocity.
