Question:
1) Two stars separated by a large distance have some force of attraction between them. If the distance between the stars then triples, assuming the masses of the stars are kept the same, what happens to the force of attraction between them, that is, does the force increase or decrease or stay the same? If the force increases or decreases, indicate by what factor (for example, "the force is 10 times as much as before").
2) Expain how a GPS (Global Positioning System) stays in orbit around the Earth since it would seem that the satellite should accelerate and fall into the center of the Earth because of the gravitational force Earth exerts on it.
3) Give one example for each of Newton's three laws of motion. Be somewhat specific with each example.
