The correct statement that describes the quantitative relationship between acceleration and net force on an object shown in the data table is:
When the net force applied to an object changes, the mass of the object remains constant.
This is because the mass is consistent (0.25 kg) for the data points provided and does not change, while acceleration varies with the net force applied. According to Newton's second law of motion (F = ma), when mass is constant, changes in net force will lead to corresponding changes in acceleration.
