equation for kinetic energy of a satellite. PHY 53 1 Satellite Motion. In relativistic mechanics this is a good approximation only when v is much less than the speed of light.
Physics Mechanics Gravity 18 Of 20 Kinetic And Potential Energy Of A Circular Orbit Youtube from m.youtube.com
Part a Enter an expression equation not a solution in numbers for the kinetic energy KE of the satellite in terms of m and v. GmM2r - GMmr TE. The kinetic energy of a satellite in a circular orbit is half its gravitational energy and is positive instead of negative.
We call these the radial and tangential velocities and write r vvv.
Newtons Law A satellite revolving in a circular orbit round the Earth possesses both potential energy and kinetic energy. GmM2r - GMmr TE. In other words the sum of the kinetic energy and the potential energy of the system is constant while energy gets transformed between the kinetic energy and the potential energy. All satellites have to be given a tangential velocity v to maintain their orbit position and this process is called orbit injection.
