Satellite in circular orbit physics. However a satellite in an elliptical orbit must travel faster when it is closer to earth. This physics video tutorial explains how to calculate the speed of a satellite in circular orbit and how to calculate its period around the earth as well. Satellites in circular orbit. Orbits above the equator remains in the same position relative to the earth s surface has an orbit time of 24 hours.

It can be shown that a more general expression for the velocity of an orbiting satellite is. Circular orbit gravity supplies the necessary centripetal force to hold a satellite in orbit about the earth. Explains the basic physics behind satellites in circular orbit. Here the centripetal force is the gravitational force and the axis mentioned above is the line through the center of the central mass perpendicular to the plane of motion.

When u and k are combined their total is half the gravitational potential energy. A circular orbit is the orbit with a fixed distance around the barycenter that is in the shape of a circle listed below is a circular orbit in astrodynamics or celestial mechanics under standard assumptions. A satellite in a circular orbit has a uniform angular velocity. E k ug e ug ug.

The kinetic energy of a satellite in a circular orbit is half its gravitational energy and is positive instead of negative. This idea was discussed through some images and video and then motion of. The circular orbit is a special case since orbits are generally ellipses or hyperbolas in the case of objects which are merely deflected by the planet s gravity but not captured. The radius of a geo synchronous orbit can be calculated from v 2 r gm ev.

Satellite in circular orbit youtube a pull or push is required to make any particle move in circle. A satellite in a geo synchronous orbit. Class 9th physics.
