She did not measure the mass after the balls hit the ground.
She did not measure the mass after the balls hit the ground.

She dropped the balls from different heights.
She dropped the balls from different heights.

She used balls that are different sizes.
She used balls that are different sizes.

She did not measure the circumference of the balls.

Answer 1

The most likely source of error in this scenario is:

She dropped the balls from different heights.

Dropping the balls from different heights would affect the time it takes for each ball to hit the ground, leading to inconsistent results in her investigation of gravity and falling objects. The other options listed are not relevant to measuring the time it takes for a ball to fall under gravity.
