critical thinking question: You weigh yourself on a very accurate scale and your weight is 170 pounds. The following week, the weight is 190 pounds. Apart from blaming yourself for a bad eating habit, what other factor can you blame for an increase in your weight ? (Hint: The weight is the gravitational force between a person and Earth: W = G*ME*M/RE2 where M is the mass of the person, RE is the radius of earth, ME is mass of earth and G is a universal constant)
