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)

Question

She used balls that are different sizes. She used balls that are different sizes. She did not measure the circumference of the balls. She did not measure the circumference of the balls. 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, in order to accurately study the effect of mass on the time it takes for objects to fall due to gravity, all balls should be dropped from the same height. If different heights were used, it would affect the time it takes for the balls to hit the ground, confounding the results.
