A particular speed of a car relative to the road has the same value in
all frames because the speeds of both the car and the road change by
the same amount.
Yes it does .. that's the closing speed (in classical physics, which is
our domain here)
Closing speed didn't exist till the idiot Einstein came on the scene.
Closing speed is just relative speed.
Velocity of the car varies. Closing speed between car and road doesn't
change
v is constant in the road frame.
KE is constant in the road frame.
Its value is X joules.
Its value is X joules in all frames.
So dimensional analysis doesn't help
Similarly, the value of 1/2mv^2 for a particular speed in one frame is
the same in all frames.
No, because speed (magnitude of velocity) is not the same in all frames.
I said "for a particular speed in one frame".
KE isn't based on closing speed .. its based on the magnitude of the
velocity.
It is based on relative velocity...same thing.
It follows that any change in that KE has the same value in all
frames.
Remember to include that in your PMM.
Nope
When a bullet comes to rest in a tree, the loss of KE is the
same in all frames.
Nope
That is not obvious until the movement of the tree is taken into
account.
All you need to take into account is the velocity of the bullet in each
frame, and its mass
I have provided the correct mathematical analysis for this situation.
And it does NOT address the change in KE of the BULLET
Look you clueless moron, can't you read maths at all?
The change in KE of the bullet is AND MUST BE accompanied by a change in the
KE of the tree. When you add the two changes together, the result is EXACTLY
frame independent.
GET IT NOW?
Gees, you're a persistent little cunt, aren't you
Well I'm deriving so much pleasure out of your persistent inability to even
understand the problem and your pathetic attempts to prop up your own argument
that it would be a shame to stop.
