1. can be shielded by the presence of an intervening mass.
2. is inversely proportional to the distance between the particles
3. is the same whether the particles are spheres of finite radius or point masses.
4. is independent of the distance between the particles.
5. can be made repulsive if the particles are made of anit-matter.

The gravitational constant G is

1. equal to g on the surface of the earth.
2. different on the moon than on the earth
3. obtained by measuring the speed of falling objects having different masses.
4. none of the above.

Some believe that the positions of the planets at the time of birth can influence the newborn.  Let's investigate this a bit. In particular the gravitational force exerted by the planets.  What is the gravitational force on a 3kg newborn due to Jupiter?  What is the gravitational pull on the same newborn by a 70kg obstetrician?
