Can I set my own bindings?

Which lets one explain situations where there is a constant velocity being applied to a mass flow... ....such as an airplane creating lift my imparting velocity to the air it passes through. Let's see if Walt wants to come out and play. Does the Kinetic Energy of a hard slab in a snowpack inclined at 43 degrees increase as its elasticity diminishes? No. -klaus -- "The iPhone doesn't have a speaker phone" -- "I checked very carefully" -- "I checked Apple's web pages" -- Edwin on the iPhone and how he missed the demo of the iPhone speakerphone. |

Alan Baker wrote: That's true (F = ma), but you can have force without acceleration. As for the rest, I don't think you have the slightest idea what you mean. force |fC4rs| noun 1 strength or energy as an attribute of physical action or movement : he was thrown backward by the force of the explosion. b" Physics an influence tending to change the motion of a body or produce motion or stress in a stationary body. The magnitude of such an influence is often calculated by multiplying the mass of the body by its acceleration. It's like kicking puppies. Go Big or Go Home Alan. That's what we say in the Jackson Hole Air Force. -- According to John Perry Barlow, "Jeff Davis is a truly gifted trouble-maker." |

Does the Kinetic Energy of a hard slab in a snowpack inclined at 43 degrees increase as its elasticity diminishes? No. kinetic energy noun Physics energy that a body possesses by virtue of being in motion. At the moment a slab releases, its elastcity is definitively 0. It lacks the capacity to rebound into its original position. Want to reconsider your answer? -- According to John Perry Barlow, "Jeff Davis is a truly gifted trouble-maker." |

No. kinetic energy noun Physics energy that a body possesses by virtue of being in motion. At the moment a slab releases, its elastcity is definitively 0. It lacks the capacity to rebound into its original position. Want to reconsider your answer? No. Kinetic energy is defined as 1/2 mv^2. The slab can lose elasticity (stiffen) without moving. A moving slab does not have zero elasticy except at the interface, which is no longer a slab. Therefore kinetic energy is zero in both cases. Quoting from a dictionary does not prove your point. It just makes you look like you don't lnow what you are talking about. Do you want to reconsider your answer? -klaus |

At the moment a slab releases, it's interface's elasticity is infinite, not zero. Its interfaces stiffness is zero, which is the reciprocal of elasticity. So when a slab releases, the interface does not decrease in elasticity, it increases, even by your perverted logic. Will you reconsider your answer now? Or will you just quote the dictionary again? -klaus |
