Four objects are each raised vertically at a steady speed. The gravitational field strength is the same in each case. Which object gains the most gravitational potential energy?
a mass of 2.0 kg raised through a height of 6.0 m
a mass of 3.0 kg raised through a height of 3.0 m
a mass of 4.0 kg raised through a height of 4.0 m
a mass of 6.0 kg raised through a height of 2.0 m
