1.One student argues that a satellite in orbit is in free fall because the satellitekeeps falling toward Earth. Another says a satellite in orbit is not in free fallbecause the acceleration due to gravity is not 9.80m/s2. With whom do youagree with and why? 2.In the law of universal gravitation, Newton assumed that the force was proportional to the product of the two masses (~m1m2). While all scientific inferences must be experimentally verified, can you provide arguments as to why this must be correct? (You may wish to consider simple examples in which any other form would lead to contradictory results.).
