A student is investigating gravity and falling objects. She drops three balls and times how long it takes each ball to hit the ground. What is the most likely source of error?
She dropped the balls from different heights.
She did not measure the mass after the balls hit the ground.
She used balls that are different sizes.
She did not measure the circumference of the balls.

The most likely source of error in this investigation is that the student dropped the balls from different heights. This would impact the time it takes for each ball to hit the ground, as the initial velocity of the balls would be different. The mass of the balls, their size, and the measurement of their circumference would not have a significant impact on the time it takes for the balls to hit the ground.
