2. Now, calculate the force of gravity between you and Earth using the equation given on page 74 in the textbook. G is called the universal gravitational constant and is equal to 6.8 x 10"l' m' kg 's 2. M and m are the masses of the two objects. In this activity M is the mass of Earth, and m is the mass of you. The distance between you and Earth is r and here it is the radius of Earth (distance from the center of the Earth to you). Do a web search and find the earth's mass in kilograms and radius in meters. Enter these values in Table A. Remember to write down the websites used in the 'References' section. First, multiply G, M and m together. Then square the r value. Then divide (GMM) by r2. This gives the force of gravity between you and Earth. The answer is in newtons, that is SI (Standard International) units of force. Enter your answer in the appropriate box in Table A. (5 points)
