A communications satellite weighs N on Earth where . What is the weight of the satellite, in N, as it orbits Earth where the acceleration of gravity is . Express each weight in lbf.
Step 11 of 5
- The weight of the satellite on Earth
- Gravitational acceleration on Earth
- Gravitational acceleration in orbit
Step 11 of 3
(weight of the satellite resting on the surface of the Earth)
(gravitational acceleration on the surface)
(gravitational acceleration while in orbit)
(weight of the satellite while in orbit)
Weight of the satellite equals its mass multiplied by the local gravitational acceleration: , therefore
Step 11 of 3
-Weight on earth
-gravitational acceleration on earth
- Gravitational acceleration while orbiting
- Weight while orbiting in and in
- The mass is constant and doesn't change with gravity.
