Mass of ball (grams) Time to hit ground (seconds) 10 1.02 15 1.01 26 1.62 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? (1 point) Responses She used balls that are different sizes. She used balls that are different sizes. She did not measure the mass after the balls hit the ground. She did not measure the mass after the balls hit the ground.

Answer 1

The most likely source of error in this experiment is: She dropped the balls from different heights.

For a fair comparison of how mass affects the time it takes for the balls to hit the ground, the balls should be dropped from the same height. If they were dropped from different heights, it would affect the time taken to hit the ground, leading to inaccuracies in the results.
