Teaching Jharkhand (JSSC) TGT (6 to 8) Mock Test 2023-24 Physics Gravitation Energy of an orbiting satellite
Satellites orbiting the earth have finite life and sometimes debris of satellites fall to the earth. This is because,
1
the solar cells and batteries in satellites run out
2
the laws of gravitation predict a trajectory spiralling inwards.
3
of viscous forces causing the speed of satellite and hence height to gradually decrease.
4
of collisions with other satellites.
