two satellites collide

To launch an artificial satellite in space, multi-stage rockets are used. It raises the satellite to a predetermined height, projects it in the right direction with a velocity which enables it to revolve around the Earth. This velocity is called the escape velocity. Escape velo..

Moon - A satellite is a solid heavenly body that revolves round a planet. The moon revolves round the earth, so moon is a satellite of the earth. The inner planets have few moons. Earth has one, and Mars has two tiny satellites. Moon The giant outer planets, ..

) use a similar mechanism. In the case of intercontinental telecommunication, two or more satellites are linked together. High frequency radio and submarine cable systems have been widely used for long- distance overseas telecommunications. The high frequency band from 3 MHz to ..

We know \ T 2 r 3 and this is consistent with Kepler's law which states that the squares of the orbital periods of the planets are proportional to the cubes of there mean distances from the sun. ..

It is the time taken by a satellite to complete one revolution around the Earth. Circumference of a circle of radius R + h is 2 p (R+h). Let T be the time period, v the velocity and h the height of the satellite above the Earth's surface. Substituting in the equa..

A particle moving along a curved path in a plane has two dimensional motion. The figure below, illustrates a two dimensional motion, where a particle moves from P (x 1 , y 1 ) to Q (x 2 , y 2 ) along a curved path. The bob oscillates along a curved pat..
