A satellite revolves around a planet in a circular orbit. What is the work done by the satellite at any instant ? Give a reason.

A satellite is revolving round the earth in circular orbit

Satellites in Circular Orbit

A satellite needs no fuel to move round a planet in a stable orbit. Why?

A satellite is revolving around earth in a circular orbit. At some instant the speed of the satellite is increased sqrt(2) times its orbital speed keeping its direction unchanged. Then, the new path of the satellite is :

A small satellite revolves around a heavy planet in a circular orbit. At certain point in its orbit a sharp impulse acts on it and instantaneously increases its kinetic energy to 'k' (lt2) times without change in its direction of motion show that in its subsequent motion the ratio of its maximum and minimum distance from the planet is (k)/(2-k) assuming the mass of the satellite is negligibly small as compared to that of the planet.

A satellite is revolving around a planet in a circular orbit. What will happen, if its speed is increased from upsilon_(0) to (a) sqrt(1.5) upsilon_(0) (b) 2 upsilon_(0)

A satellite moves around the earth in a circular orbit with speed v . If m is the mass of the satellite, its total energy is

In circular orbit of a satellite

The orbital speed of a satellite revolving around a planet in a circular orbit is v_(0) . If its speed is increased by 10 % ,then
