Which of the following statements about mass is true? A. Mass is the same regardless of the size of an object. B. Mass does not depend on gravitational pull. c. Mass is the amount of gravitational pull on an object. D. Mass is different in different locations.

Find the absolute value of the change of the gravitational potential energy (gpe) of the puck-earth system from the moment the puck begins to move to the moment it hits the spring. use 0.253 m for the displacement of the puck along the ramp and 9.80 m/s2 for the acceleration due to gravity. assume that the mass of the puck is 0.180 kg.
