The student can improve the investigation by dropping the balls from the same height. This ensures that the only variable being tested is the mass of the balls, allowing for a clearer understanding of how mass affects the fall due to gravity. Different drop heights could introduce additional variables that might affect the results, such as air resistance and impact time. Keeping the drop height constant will make the investigation more controlled and reliable.
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)
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 finding balls made from different materials by finding balls made from different materials by measuring the circumference of the balls
