A satellite can also be placed in Low Earth Orbits (about 1,000 kilometers above the Earth (between 400 miles and 1,600 miles)). However, satellites in LEO need a...
Polar Orbit The Polar Orbit is not much suitable for communication purposes because it moved in a different direction than that of direction of earth’s rotation. So, the...
Important points The height of the geostationary orbit is 35786 kilometers above earth In Geostationary Orbit, the satellite moves with an orbital speed of 11068 km per hours....
Satellite refers to any project that is orbiting earth, sun or other planetary bodies. Satellites can be artificial or natural. The artificial satellites basically work on principle of...
In the early 1600s, Johannes Kepler proposed three laws of planetary motion as follows: Kepler’s First law (Law of orbits) Each planet moves around the sun in an...

Uniform Circular Motion When a particle moves in a circle with a constant speed then the motion is known as uniform circular motion. We can consider an object...
When an object is thrown from horizontal at an angle θ except 90°, then it will follow a trajectory and the motion is called projectile motion. A horizontally...
