The best way for the student to improve the investigation is by dropping the balls from the same height. This ensures that the only variable being tested is the effect of the balls' mass on their fall, allowing for a more accurate assessment of how gravity affects objects of different weights.
Question 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 A student designs an investigation to study the effect of gravity on objects on Earth. He will use the criteria shown. How can the student improve the investigation? (1 point) Responses by finding balls made from different materials by finding balls made from different materials by using balls that are the same mass by using balls that are the same mass by dropping the balls from the same height by dropping the balls from the same height by measuring the circumference of the balls
