Physics for JEE 2016: Projection of Satellites and Spaceships & Applications of Kepler’s Laws

Spaceships can be launched from earth to space in different ways. To launch a satellite it has to be launched at specific speeds at different altitudes where the speed depends upon the shape of orbit or the trajectory in which it has to be set.

Watch the below video for understanding of trajectory of spaceships and satellites in motion around a planet in its gravitational field.

Depending upon the speed of projection at an altitude the spaceship can be setup in circular orbit, inner ellipse, outer ellipse, parabolic or hyperbolic trajectory. All such cases are useful in different types of space missions.

Kepler’s Laws can be used in different types of problems based on cases of satellite motion. See the Example videos below for understanding of applications of Kepler’s Laws.
