1.One student argues that a satellite in orbit is in free fall because the satellite keeps falling toward Earth. Another says a satellite in orbit is not in free fall because the acceleration due to gravity is not 9.80m/s2.

Question

1.One student argues that a satellite in orbit is in free fall because the satellite
keeps falling toward Earth. Another says a satellite in orbit is not in free fall
because the acceleration due to gravity is not 9.80m/s2. With whom do you
agree 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.).
