What is the evidence?
In our experiment, the blocks had different masses, 20 g., 30 g., 44 g., 123 g and 142 g but the time for all five blocks to fall was about the same. It took between 1.5 and 1.8 seconds for them to fall. No, mass does not affect how quickly an object falls. Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls.
