She dropped the balls from different heights.
She dropped the balls from different heights.
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 did not measure the circumference of the balls.
She did not measure the circumference of the balls.
She used balls that are different sizes.
1 answer
The most likely source of error in this investigation is:
She dropped the balls from different heights.
This is because if the balls were dropped from different heights, the time it takes for each ball to hit the ground could be affected, leading to inaccurate comparisons of the effects of mass on falling time. The other options do not directly impact the measurement of fall time in the context of this experiment.
