Jolon is correct. The change in gravitational potential energy is zero in this case. Part 12 of 12 - Analyze Now Jolon and Terry tackle a problem. A block of mass 1.5 kg is attached to a horizontal spring that has a force constant of 2.40 x 10' N/m, and is free to slide on a frictionless surface as shown. The spring is compressed to x, = -5.5 cm by pushing on the block, and then the block is released....
