The student can improve the investigation by dropping the balls from the same height. This is crucial because it allows for a controlled comparison of the effects of gravity on the different objects without the variable of differing drop heights affecting the results. By ensuring that the drop height is consistent, the student can more accurately assess how mass affects the fall of the objects.
Use the table of criteria for an investigation to answer the question.
Object To Be Dropped Drop Height (meters)
10-gram ball 5
5-gram ball 8
18-gram ball 10
