Explain why a satellite does not fall back to Earth? What are the forces acting on the satellite and in what direction are they pulling the satellite.
The satellite is being pulled to Earth by gravity, and at the same time its inertia is pulling it out towards space. This creates centripetal force on the satellite, causing it to orbit the Earth in a circular pattern. It does not fall back to Earth because the Earth curves underneath it and if it does try to fall it misses the Earth.
