Question

A science class is planning an investigation about gravity and objects on Earth. In three to four sentences, explain the steps the class should take to provide data to help them make a conclusion about the effect of gravity on objects of different masses. Please keep the answer short and simple

Answer 1

Pick several objects with different masses (ideally similar shape/size to reduce air resistance) and measure their masses. From the same height, release each object without pushing and measure the fall time with a stopwatch or video, repeating each drop several times. Record and average the times for each mass while keeping height and release method the same. Compare the average times to see whether heavier objects fall faster (they should fall at the same rate if air resistance is negligible), and use the data to support your conclusion.
