i've always wondered, when newton dropped the cannon ball from the ship mast to proove his theory of projectile motion, why didn't the cannon ball break the deck and sink the ship!!?? any ideas?

 

[Jellymonsta]

v. small cannon ball
and he wouldnt have fired it... just dropped it.

Dood, you got gallileo confused with newton. Gallileo dropped a ball of some sort from the mast of the ship to show that the ball shared the boats motion and hence was in an inertial frame of reference as the ball landed in the bucket at the base of the mast.

Newton "hypothesised" about firing a cannon from a "really tall mountain" so that it would go into circular orbit.

 

[Ace-Pilot]

LoL, yeah Alexz is right.

It was actually gallelio that droped the ball from top of a moving ship.

 

[superhubert]

good point......but you didn't answer the question.....

to jellymonsta, very small cannon ball? has anyone told you you can kill someone by dropping a coin from a tall building? the cannon ball must have been a ball bearing!!!

 

[BlackJack]

... what if it wasn't a cannon ball? galileo could've dropped any type of ball, like a leather football. It wouldn't have broken the deck because it wasn't iron...

Lots of these stories aren't entirely accurate. Galileo didn't prove all weights fall at the same speed from the leaning tower of Pisa either... the results there were inconclusive, he had to do it another way.

Also, imagine nerd Galileo carrying a beeeg, heavy cannball while climbing the mast... even the sailors would have a hard time going up with both hands tied.

 

[superhubert]

they could have rigged up a pulley sytem to winch the cannon ball up.. but anyway, why did i start this thread, it's stupid

 

[beava_69]

im set for a question on weahter the cannon would break the ship then

 

[BlackJack]

Look at it.. it's a very good excuse not to study.
Neither mgiht the sailors be interested in letting Galileo drop a cannon ball on their decks either.

 

[Jellymonsta]

but what if it was galileo's ship? hes entitled to throw cannonballs around it if he wants to.

 

[BlackJack]

Galileo isn't rich, he wuldn't have the money to buy one. His father didn't own a ship either... he'll have to settle for nen-destructive ways to prove his theory...

 

[McLake]

Maybe it was an egg ...

 

[superhubert]

I'VE GOT IT!!!! sailors are all stupid... they wouldn't have believed him that the cannon ball would drop on the deck, they would have thought it would have landed behind the boat....stupid sailors....I'll bet Galileo had hell to pay when he prooved himself right.........

 

[Wintermute]

No way. He just had someone at the bottom to catch it

 

[SgtSlick]

The boat sunk!!

Think about it.

Using F=ma and assuming the ball was "dropped" and weighed 15 kg

F=15x9.8
F=147N

W=mg
W=147x9.8 (maybe a fraction less as he was above sea level hehe)
W=1440.6, thats fucken huge!! He damn sunk the ship, and just paid to have it all kept secret...In fact it was a conspiracy!

MUWAHAHAHAHA

 

[superhubert]

i hope we get a q on this.........

 

[molloby]

I'm pretty sure he dropped a dagger...

 

[McLake]

Forget what I said about the egg, it was a water balloon ...

 

[BlackJack]

Now you see now how fake rumours can be? Ahhhh....
I really hope we will get a q on it too... too easy.
