On your lab table, you have a variety of objects available with different shapes, sizes and masses. Based on this collection of objects, state at least three predictions (each based on a different feature, such as shape, size and mass) that you can test using this equipment. For each prediction, state what this test would indicate about the underlying physics and perform any additional possible tests to support or refute this idea. For example, a student might predict: \"The ball with the largest radius will get to the bottom faster than the balls with smaller radii. This might indicate that all objects with larger radii will get to the bottom faster, so we will also test hoops of different radii.\" Think about how you can reduce experimental error, and apply these methods
