6.3 Exercise 15

Avg difficulty 2.5

Two friends are having a conversation. Anna says a satellite in orbit is in free fall because the satellite keeps falling toward Earth. Tom says a satellite in orbit is not in free fall because the acceleration due to gravity is not 9.80m/s29.80 \text{m}/\text{s}^{2}. Who do you agree with and why?
