Correction. Only for constant mass. Otherwise it is F = d/dt(mv).


Correct. 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.

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.

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?

Oh. How does an airplane wing change mass?

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?

I was thinking that it makes him look like an English major (not that
there's anything wrong with that).

Jeff.. I was thinking about this, and you are backwards. 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?
