26. Astronauts who waked on the moon felt as if they weighed about one sixth of their weight on earth. this is because the weight of an object is determined by the gravitational attraction between the object and the planet (or moon) its on. you can use the following formula to estimate the weight of an object on the surface of any of the planets: gravitational force=GmM/r^2, where G=universal gravitational constant,m=mass of the object, M=mass of the planet, and r=radius of the planet. For a given object, Grandma remain constant, so the force of gravity depends only on the variables named r.
