Define orbital speed of a satellite.

Define critical speed of a satellite. Derive an expression for it.

The value of escape speed from certain planet is 4 km/s. What will be the orbital speed of a satellite orbiting close to its surface ?

In previous question calculate orbital speed of satellite.

Statement-1: A satellite is moving in a circular orbit of the earth. If the gravitational pull suddenly disappears. Then it moves with the same speed tangential to the orginal orbit. Statement-2: the orbital speed of a satellite increases with the increase in radius of the orbit.

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

The value of escape velocity on a certain planet is 2 km/s. Then the value of orbital speed for a satellite orbiting close to its surface is

The ratio of the orbital speeds of two satellites of the earth if the satellite are at heights 6400 km and 19200km (Raduis of the earth= 6400 km )

The critical speed of a satellite of mass 500 kg is 20 m/s. What is the critical speed of a satellite of mass 1000 kg moving in the same orbit ?

Define orbital velocity of a satellite. Derive expressions for the orbital velocity of a satellite. Show that the escape velocity of a body from the earth's surface is sqrt2 times its velocity in a circular orbit just above the earth's surface.
