Students want to design an experiment to study gravity. They decide they will drop four objects with the same mass from the top of their school’s bleachers. They will time how long each object takes to reach the ground. How can they improve confidence in the experiment’s results?(1 point)

The best way for the students to improve confidence in the experiment's results is to:
Drop each object 10 times and use the average of each object’s fall times.
By conducting multiple trials and averaging the results, the students can account for any variations in timing due to human error or environmental factors, leading to a more reliable and accurate measurement of the fall times for each object.
