Answer 2

Answer:

1. The sum of their masses
2. Is opposite to the direction of motion
3. acceleration
4. Gravitational attraction between satellite and earth
5. 6.67 * 10 -11 N/m2/kg2
6. Issac Newton
7. elliptical
8. Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
