Question
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)
Responses

To improve confidence in the experiment's results, the best response would be:
**Drop each object 10 times and use the average of each object’s fall times.**
This approach helps to account for any variability in timing and environmental conditions, allowing for a more accurate measurement of the time it takes for each object to reach the ground. Averaging multiple trials reduces the impact of any outlier time due to human error, wind, or other variables, leading to more reliable results.
