Explanation 1) Concept: The difference between Potential energy on the earth surface and at height h will give us ( ∆ U ) . By comparing it with the kinetic energy of the orbiting satellite at height, we can calculate (h). Using the same equation, we can decide the greater quantity between ∆ U a n d K . 2) Formula: i) ∆ U = U f - U i ii) U f = - G M m ( R + h ) iii) U i = - G M m ( R ) iv) K = G M m 2 ( R + h ) 3) Given: ∆ U = K 4) Calculations: a) Calculation for h: ∆ U = U f - U i ∆ U = - G M m ( R + h ) - - G M m R … … … ( 1 ) K = G M m 2 ( R + h ) … … … ( 2 ) Equating equation (1) and (2) 1 R

Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force betwe…

Students have asked these similar questions

A certain satellite has a kinetic energy of 8 billion joules at perigee (The point closest to earth) and 5 billion joules at apogee(Point farthest from earth). As the satellite travels from apogee to Parigi, how much work does the gravitational force due on it? Does its potential energy increase or decrease during this time, and by how much?

A certain satellite has a kinetic energy of 8 billion joules at perigee (the point at which it is closest to Earth) and 5 billion joules at apogee (the point at which it is farthest from Earth). As the satellite travels from apogee to perigee, how much work does the gravitational force do on it? Does its potential energy increase or decrease during this time, and by how much?

A satellite on a circular low Earth orbit moves at a constant speed and is subject to the gravitational force of the Earth. Is there any work done on the satellite. Explain your answer.
