Use the table of data from an investigation to answer the question. 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 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 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.

Answer 1

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

This is because the time it takes for an object to hit the ground under the influence of gravity should be the same for all balls if they are dropped from the same height, regardless of their mass. If the balls were dropped from different heights, it would affect the time measurement, leading to inconsistent results.
