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

Answer 1

The most likely source of error in this investigation could be human reaction time in starting and stopping the timer. Since the student is manually timing the balls as they fall, there could be variation in the starting and stopping of the timer, resulting in inaccurate measurements. Additionally, factors such as air resistance, wind, or uneven ground surface could also affect the timing of the balls falling, leading to errors in the measurements.
