Sample result
A sample exchange: why do heavier objects not fall faster?
Why don’t heavier things fall faster? It seems like they should.
Conversation
- SocratesGood question. If you dropped a brick and a feather, what would happen?
- YouThe brick lands first.
- SocratesWhat might be slowing the feather down that is not slowing the brick much?
- YouThe air? It kind of floats.
- SocratesSo imagine two bricks taped together beside one brick, both dropped. What does your first idea predict?
- YouThe double brick should fall faster… but it’s just two bricks falling side by side. Why would taping them change anything?
- SocratesThat is very nearly Galileo’s own argument. So what really decides how fast things fall when air is not in the way?
Where you ended up
Without air resistance, all objects fall with the same acceleration. You reasoned it out yourself, and Socrates has noted it as something to connect to gravity and mass next time.
