The most likely source of error in this investigation is "She dropped the balls from different heights." Since the time it takes for an object to hit the ground is influenced by the height from which it is dropped, if the balls were not dropped from the same height, it could lead to varying times that are not solely due to differences in mass. The other options regarding circumference, mass measurement after hitting the ground, and size do not directly affect the time of free fall in a vacuum, assuming air resistance is negligible for the sizes of the balls used.

She drops three balls and times how long it takes each ball to hit the ground. What is the most likely source of error? (1 point) Responses She did not measure the circumference of the balls. She did not measure the circumference of the balls. She used balls that are different sizes. She used balls that are different sizes. She dropped the balls from different heights.
