The International Space Station (ISS) orbits the Earth in a nearly circular orbit that is 345
km above the Earths surface.
(a) How many hours does it take for the ISS to make each orbit?
(b) Some of the experiments performed by astronauts in the ISS involve the effects of
“weightlessness” on objects. What gravitational force does the Earth exert on a 10 kg
object in the ISS? Express your answer in newtons and as a fraction of the force that
Earth would exert on the object at Earth’s surface.
(c) Considering your answer in part 2(b) above, how can an object be considered weightless
in the ISS?
3. Two planets, both of mass m, are separated by a distance d. Their relative velocity is negligible, and there is an inertial frame in which both planets are essentially at rest. The gravitational potential u(r) at the position r in the presence of the two planets, located at R1 and
R2, is given as
u(r) = −
Gm
R1 −r

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.
Let's say an apple weighs exactly 1N on the surface of the Earth (which corresponds to a distance of 6400 km from the center of the Earth). Now imagine an astronaut brings the apple on a spaceship. What is the force of the Earth's gravity on this apple at a vertical distance of 6400 km above the surface of the Earth?
Hint: the radial distance of the apple from the center has doubled. What does this do to the force of gravity according to Newton's law of universal gravitation?
