Objects 1 and 2 attract each other with a gravitational force of 36.0 units. If the distance separating objects 1 and 2 is changed to one half then what is the new gravitational force

Using software, a simulation of a javelin being thrown both on earth and on the moon is created. in both cases, the velocity and angle of projection are kept the same. on earth, the javelin covers a distance y. what distance would it cover on the moon? (the moon’s gravity is about 1/6th that of earth.) a. 6y b. 6/y c. y/6 d. (y+6)2
