Two satellites orbit Earth at the same altitude. One satellite is more massive than the other. Which statement is true of this particular situation?  a) The heavy satellite moves faster  b) The light satellite moves faster  c) The satellites have the same speed  d) Which satellite is faster depends on their altitude

= 400 kg with their centers 8 meters apart. If you In the simulation, start with mị = 200 kg and m2 want to increase in the gravitational force between the two masses by the greatest amount, should you double the mass of m2 or should you halve the distance between the masses? In one or two sentences, explain which option would create the greater increase in the gravitational force and why.

The gravitational force between two objects is represented by the variable F. If the masses are both doubled and the distance is halved, what is the new gravitational force?   Question 9 options:   F   16F   34F   13F

What is the approximate escape speed in m/s from a tiny moon in orbit about Mars that has a mass of 0.97 x 1016 kg and a radius of 10.0 km. The gravitational constant is 6.67 x 10-11m3kg-1s-2
