What did Newton conclude about the force that pulls apples to the ground and the force that holds the moon in orbit? (12.1) inertia If the moon falls why doesn't it get closer to the earth? (12.2) its a Projectile circling the earth blyow WW under the attraction of gravity Calculate the force of gravity on a 1-kg mass at the earth's surface. The mass of the earth is 6 x 10^24 kg and its radius is 6.4 x 1076. (12) gem achi no evert grants Thioz zsob poofig ment How does the gravitational field strength at the surface of the earth compare with the jugunail acceleration of free fall? (13.1) Why would the earth not be sucked into the sun if it became a black hole? (13.6) Why doesn't gravitational force change the speed of a satellite in circular orbit? (14.2)
