Answer this question: One 7. 0 kg bowling ball is lifted to a storage shelf 1. 0 m above the floor. A second 7. 0 kg ball is lifted to a storage shelf 2. 0 m above the floor. Which of the following best explains why the measured force of gravity on each ball is nearly identical. Choose from: + The final potential energy of each ball increased. + The amount of work required to lift each ball is identical. + The distance of each ball from Earth's center of mass is almost identical. + The gravitational force of each ball on the other cancels out the force of Earth's gravity. .
