To investigate the effect of gravity on objects of different masses, the science class should first select a range of materials with varying weights, such as a tennis ball, a rock, and a feather. They should then conduct a series of drop tests from the same height to observe how long it takes each object to reach the ground. By timing the falls and recording the data, they can compare the results to see if mass affects the rate of descent. Finally, they should analyze their findings and draw conclusions about the influence of gravity on objects of different masses, discussing any anomalies and what they might indicate.
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.(4 points)
