Fire the gun over an open area so the bullet does not hit anything...at the exact same time drop the bullet that is in your hand. Which bullet hits the ground first?
****Both hit the ground at the exact same time even though the one fired from the gun travels a mile. This is because all objects fall at 9.8 m/s-squared. The fact that one is traveling makes no difference! |
Bullet you drop doesn't even have to be the same weight or size, as long as it's not like a feather or something. Galileo proved this. The equation is very slightly off because the fired bullet is spinning and there's an aerodynamic component that may keep it aloft fractionally longer, but do the experiment in a vacuum and it's absolutely true.

Since it's a science "wonder if" then you must take the curve of the earth's surface into account, and the dropped bullet would land first. I wonder about watermelons though.

I have effectively dealt with my obsessive disorders:
I made a macro that automatically pushes the 'update' button and sends me an e-mail every time there is a change in votes, views, comments, faves or thread activity. I have an e-mail alerting mechanism in my bedroom at my office as well.
This way I don't have to obsessively push the 'update' button all the time. :P |

Yes Bear you are correct. It can be a 16 pound bowling ball and a bullet...in a vacuum.

Both the truck and I are traveling at, say, 50 mph. When I jump, I am still traveling 50 mph. Air friction will slow me down a bit, but how much over the distance I have jumped? I think practically none... I don't think an unaided human can jump high enough to fall out of a moving truck, unless he is already at the very tailgate to begin with.

Just as well, otherwise we'd all be in trouble if we decided to jump inside a moving aircraft. |

Raised and trained dogs (mostly show dogs) for a long time and in my experience when they seek out hiding in small spaces it usually means they are not feeling too good and find security in confined spaces |

I read somewhere (can't remember the source) that a persons adult life is determined by three yes/no decisions made before the age of 21. |

I got to thinking, as well, watching my dog.
I wonder if the dog species in general is able to lick themselves only because they can not make a fist.

In its liquid state it bonds with the molecules of the metal surface; when it dries it's a bonded-on film.
Glad you asked?

Dogs are the way humans should be; very accepting. When they need something it generally appears. No big surprise. When it doesn't they wait patiently. |

From you image of Karma, I thought she didn't have a butt...... |

I've done some aerodynamic research at their facilities and there are actually three of them there. The employees are flown in and out on the same jets as the engineers. |
