Question

Derive an expression for the total energy of satellite orbiting the earth what is the significance of negative total energy​

Answer 1

Answer:

The total energy of the satellite is hence negative, which means that the satellite will never be able to escape from the gravitational pull of the planet.

Answer 2

Answer:

Gravitational energy of satelite

Explanation:

U= -GMm/r ----------1

k.e=1/2m.vo^2 ------2

vo^2=Gm/r ---------3

put the value of 3 in 2

k.e =1/2m.GM /r

K.e=1/2(GMm/r) --------4

Total energy of satelite

E=K.E +P.E

E =1/2 (GMm/r) - (GMm/r)

E=. -GMm/2r+GMm/2r=0

where the negative sign show that

satelite is bounded to the earth
