Newton's Law of gravitation is represented by
what is the SI unit of the proportionality constant G.
The gravitational force F between two bodies of masses m1 and m2
where G is the gravitational constant (6.672 × 10−11 N m2 / kg2), m1 and m2 are the masses of the bodies in kilograms, and r is the distance between the two bodies. Write a function to calculate the gravitational force between two bodies given their masses and the distance between them. Test your function by determining the force on an 800 kg satellite in orbit 38,000 km above the Earth. (The mass of the Earth is 6.98 × 1024 kg and the radius of the Earth is 6.371 × 106 m.)
Two small objects, with masses m and M, are originally a distance r apart, and the magnitude of the gravitational force on each one is F. The masses are changed to 2m and 2M, and the distance is changed to 4r. What is the magnitude of the new gravitational force? D) F/2 A) 4F B) F/16 C) F/4 E) 16F
