Kepler developed which of the following ideas?
• An object in motion stays in motion until acted upon by an unbalanced force.
• Planets move in elliptical orbits with the sun as one focus.
• The force of gravitational attraction is inversely proportional to the square of the distance between the objects.
• The planets carve out equal areas in equal time intervals.
• The square of the radius divided by the cube of the period of a planet's motion around the sun is a constant.

Four satellites in circular orbit about the Earth are all orbiting at 250 km above the surface of the Earth:
Satellite A: m = 4000 kg
Satellite B: m = 5000 kg
Satellite C: m = 6000 kg
Compare their orbital speeds.
• A = B = C
• A > B > C
• C > B > A
