Textbook Question
Chapter 4, Problem 124DQ
As part of their training before going into orbit, astronauts experience weightlessness when riding in an airplane that is flown along the same parabolic trajectory as a freely falling projectile. A classmate says that gravitational forces on everything inside the plane during this maneuver cancel to zero. Another classmate looks to you for confirmation. What is your response?

A satellite is traveling around a planet in a circular orbit with radius R. It moves in a constant speed of v = 1.02 × 104 m/s. The mass of the planet is M = 5.94 × 1024 kg. The mass of the satellite is m = 4.7 × 103 kg.
Enter an expression for the magnitude of the gravitional force F in terms of M,R,m and the gravitional constant G.
Enter an expression for the radius in terms of G,M and R.

Topic: Gravitational Force
Let's say that I want gravitational force Fg = 1.00 N. what combination of m1, m2, and r will give that?
Hints: There are many possible answers, you just need to find one. To avoid trial and error, you can pick values for m2 and r (distance) then use Newton’s law of gravity to find the m1 value giving Fg = 1 N.

- Every few months, memes circulate claiming that certain alignments of the planets with the Earth will result in a change in the gravitational force you feel. Usually these memes state that the alignment will counteract Earth's gravity slightly so you will feel less of a gravitational pull towards the Earth. Can this ever happen? Let's look at the numbers. What is the gravitational force (in N) of the Earth on you (MĚ = 5.97 × 1024 kg, R₁ = 6380 km)? Say your mass is 64 kg. (Enter the magnitude.)
