It's applying the same force to lift/drag the log the entire time
What you're seeing is the log raising, and the drag/friction from the ground and gravity being overcome causing it to appear much faster. Look at how the log hits the bed of the truck before speeding up. That removes much of the force needed to "lift" the log, and it slides in easily after that point

>Actually "your" is correct in this instance. "You're" is the contraction of you are. Your is a possessive pronoun.
>The possession in this case is one's speed
Nether of which make "your going in the opposite direction" correct

Wind speeds and other things can factor into this, too
Also, you're.

I just find it funny that it's a CBC link (Canadian Broadcasting Corporation), and then reads /Canada/north/Alaska
...which is obviously not appreciated by others here

Reply to comment by chancellortobyiii in A wormhole that connects two points in space where the strength of gravity is different would let you violate the 2nd law of thermodynamics. by chancellortobyiii
Again, you're looking at a very narrow scope for the question you're posing. It's not gaining energy at all, since the Earth would be exerting the same amount of energy on it regardless.
Had your wormhole pulled it from a pure vacuum that cannot actually exist in real life, your 'misguided notions' would be correct. However, the energy in the system has not changed at all; the location of your theoretical billiard ball has. Now if we extrapolate the energy distribution over time across a large timeframe, unless we'll assume that that billiard ball is undergoing infinite "nudges" into said wormhole [all of which you're conveniently ignoring as energy going into the system], then that ball falling in a single instance is no different from one at a standstill in reference to the Earth.
For such a theoretical, large scale question, you sure are focused on the minutiae.
And wouldn't it be better just to use Newton's Laws, which the laws of thermodynamics are derived from anyways..?

How are you missing that the ball is not gaining any energy? That energy is simply being applied to the ground all the time in the case of the one on the ground, and the one falling is gaining energy to try and match the one that seems to be "at rest".
Are you aware of [elastic] potential energy? Or yhe energy contained in chemical bonds? A spring sitting under compression? Just because they are 'at rest' in reference to one thing doesn't mean they contain no energy in that system. You're just looking at the wrong things.
Also, how is any of this related to thermodynamics? I'm pretty sure all of those laws have to do with heat transfer...

Assuming this wormhole as an object needs to exist in equilibrium, it would have to consume matter at a rate equal to the energy released.
Your example is somewhat flawed, even with a basic example of centrifugal and centripetal motion. You're basically saying that the centrpetal motion we understand as gravity is bypassed, allowing the object to "gain" energy from falling. It would've actually been under more energy/force closer to the Earth, and has lost energy by rising. The falling is just the re-equalizing of the potential energy to the point where that object in its surroundings exist most stably.
Also you go from saying "objects will gain more energy" to saying "it'll take more energy to open a wormhole than any potential use of it would be worth". Did you have a point, or were you trying to contradict yourself?
You're also assuming things pass through undistorted. Say you drop something extremely dense through, like lead, does it face any compression? The release of energy on exiting such a wormhole would be where that equalizes; the systems would maintain that energy as the object moves through each stage.
Assuming that a "wormhole" acts as a portal is silly, if such a thing were to exist and you assume it has either extremely high or extremely low gravity, it would need to be adjusted approximately to travel through this wormhole. Just because gravity differs doesn't mean everything else doesn't apply. If gravity is so high, the amount of energy required to move something across it would be insane. If it were extremely low, the shear forces would reach atomic levels quickly, essentially dissolving anything that entered with any energy (assuming it's essentially a vacuum). To account for this would be extremely difficult.
