 Satellite What is satellite and satellite easy definition ?  In Physics, An object revolving around the planet in a particular orbit is called satellite. There are two types of satellite are  Natural satellite and Artificial satellite. The moon is a natural satellite of the earth.The manmade satellite like Aryabhatta ,Nirbhaya , Chandrodaya etc. revolving around the earth are known as artificial satellite. Launching of satellite 1 . For projection of satellite minimum two stage rocket is used the satellite is keeping at  the tip of the rocket and the first stage of fuel is ignited on the surface of the Earth  so that rocket rises to a desired height above the surface of Earth. 2 . When satellite attains desired height the first stage of rocket is detached and the rocket is rotated to 90 degree with the help of remote control. 3 . After that the fuel in the second stage of rocket is ignited so that it is projected in horizontal direction. 4 . When the fule in the second stage is comp

 Centripetal force & Centrifugal force What is centripetal force ? Centripetal force definition :- A force acted on a particle performing circular motion along the radius and towards the centre of circle is called centripetal force. As there is no displacement in direction of centripetal force hence it does not perform any work. Centripetal force is also called real force. Centripetal force is given by (formula of centripetal force) Fc= mv sq/r  Example for centripetal force (1) Moon revolve around the earth  in circular circular orbit. A centripetal force required for the circular motion of the Moon is provided by a gravitational force of attraction between Earth and Moon. (2) In atom electron revolves around the nucleus in circular orbit. The centripetal force required for the motion of electrons is provided by electrostatic force of attraction between positive charge nucleus and negative charge electron. (3) It is a real force arising from gravitational or electromagnetic intera

Definition and Formules                                    CIRCULAR MOTION CIRCULAR MOTION DEFINITION The motion of partical along the circumference of circle is called circular motion . Circular motion is of two type uniform circular motion and non-uniform circular motion . Uniform circular motion The motion of particle in which its speed remains constant is called uniform circular motion.  Non uniform circular motion  the circular motion of particle average speed of particle goes on changing use cal non uniform circular motion. Angular displacement An angle traced by a radius vector at the centre of the circle is called angular displacement, Angular displacement is represented by 𝚹 its unit is radian is direction is given by Right Hand Thumb Rule. Angular velocity The rate of change of angular displacement with respect to time is called angular velocity. Its unit is rad/sec and distance is along the axis of circular motion and given by Right hand Thumb Rule. Angular acceleration  Th
