Measurement and CER Practice Test

Question – Does an object’s mass affect how quickly it falls?
No, mass does not affect how quickly an object falls. 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. Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls. 
What's the evidence?

• No, mass does not affect how quickly an object falls
• 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.
• Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls.
