It's a tragedy of immense proportion. But, guns are something we have the right to own. It's all in the sale of firearms and the background check. It MUST get tougher and much more thorough. I received my CCW permit over 2 yrs ago. I have not fired my weapon since. A person can own a gun and not...

An Imam is the officiating priest in a mosque.

Matt, the beast you call friction is a very large, complicated variable. It has a myriad of different applications for all things that rub... You have not given us a physics problem, you have sent out a 911 call for 411 findings. Good Luck. P.S. Go to tricipedia...

Eddy currents are not always circular. They are susceptible to the magnetic field homogeneity. They are somewhat circular due to the electromagnetic field which can be easily demonstrated with the right hand grip rule.

There are several things here that need to be addressed... 1) how far did it drop ? 2) There is no way that anyone can comment on the crater impact component without knowing what state the surface is in... clay, cement, dirt that hasn't seen water for years... At best F = ma 9090.9 Kg x 1.52...

The velocity is your constant... It's an electromagnetic propagated wave... it moves at the speed of light. The variables that can be changed are wavelength and frequency.

Asymptotic : You can come, forever closer, to infinity, but it will never touch.

Pure and simple... the speed of light is an asymptotic entity. Nothing can reach it, that alone, pass it.

Magnetic force on the metal surface is inversely proportional to the distance. I feel the plywood, a non ferromagnetic material, should not have any significance to the outcome.

I have admired physics and the physicist themselves, for over 30 years. The equations are a thing of scientific and mathematics splendor that make me want to look further and further into its vast presence. I'm interested in all of the fields that have emerged over its lifetime. I'm not a...
