  • CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Hi there!

So I got to thinking, and I was wondering if someone would explain this to me in English:

Suppose I place a tennis ball atop a basketball and climb to the top floor of the Taj Mahal in India and drop them onto the street below.

The basketball hits first and bounces a few feet in the air, but the tennis ball, atop the basketball, will rocket into the air like a firecracker.

Why is that?

I thought about it, but decided against.

Mainly because it didn't involve a miracle to be explained.

It's just a simple (but pretty cool) physics question. The only challenge would be if someone could take the five seconds required to google the answer, which would take you less time than posting s thread in here and waiting for replies.

Are you sure?

It looks pretty miraculous to me... ball bouncing higher than it falls.

Nothing miraculous. It's plain and simple law of conservation of energy and law of conservation of momentum at work

It actually happens in a more natural environment. Observe a drippy faucet down a bucket of water. Sometimes, the splashes will actually fly higher than where it came from!

You cannot turn this concept into a perceptual motion machine because energy is conserved.
