Please don't start a war.. This is supposed to be a topic about sticky rails. Not minecraft physics. But if you do want to argue on physics. Go to the appropriate threads and talk about AE's matter to energy system or endermen.. maybe even creepers?

Wow. Put a minecart on a sloped rail, walk off a cliff, throw an item out of your inventory, guess what? falls! why? because yes, gravity does not apply to all blocks, but it does apply to some entities (including minecarts)

Edit: there should be a rule that only allows people with reasonable intelligence to suggest mods and features for the game.

Over 90% of all the things in Minecraft ignore gravity. Also, THIS IS A VIDEO GAME! Stop trying to apply real world logic to it. Gravity exists, but only to CERTAIN THINGS! And there are PLENTY of ways around gravity. In Minecraft, gravity isn't universal.

Oh, and if your rule is implemented, then i guess you won't be able to post any suggestions.

Yes, but even so im fairly sure a sticky rail will slow down the minecart if anything. Regardless it's not Mojang even looks at this forum so why do I care.

Actually, they do, and HAVE posted on ideas, if you are going to be rude, please do not continue to post on my thread. Thank you

I agree, that you have a point, but there is one major flaw with it: It is wrong.

You do argue that the acceleration of a booster rail is not enogh to counteract the acceleration of the gravity of a minecart. It is obvious that this only applies to vertical climbs, since minecarts are already able to move up slopes and move horizontally.

You furthermore argue that the decceleration of a minecart would happen so quickly, that mincart would not be able to transition from a normal slope to an upside down one, as the minecart would not be able to surpass the one vertical rail in the middle.

This is where it becomes interresting. The acceleration of a minecart by gravity is 16 meters per second². (Source: minecraftwiki). Now we have to compare this with the acceleration of a booster rail. Sadly, there are no literature values on this one. (At least I could not find any), so I had to test it by myself. According to my tests, accelerating minecarts are able to travel 10 Blocks in 1.4 seconds. This leads to an accelaration on the rail of: 10/1.4²= ca. 5.1 m/s². This value is not good by any means, and I would appreciate if someone could come up with a better testing method or result. (Just reply, I will not hesitate to change this post).

Seeing ths values, it becomes obvious that a vertical climb is not sustainable, so the minecart cannot go straight up indefinantly.

However, the real question is: Can a minecart transition to a upside down slope?

To answer this question: We have to calculate when the velocity of a minecart is fully deccelerated by the gravity minus the booster accelaration. The decelaration of the minecart, therefor is 10.9 m/s². The maximum velocity of a minecart going up a slope is the root of 2 times 8m/s= ca. 11.31m/s. This leads to the conclusion, that the longest time a vertical climb can be sustained is: (11.31m/s)/(10.9m/s²)= 1.04 seconds.(=t_1)

How many blocks can a minecart travel vertically given the time of 1.04 seconds and the decreasing velocity. If the number of blocks is greater than one,this post does make sence and cannot be critizised in this aspect. The number of blocks is equal to the integral from 0 to 1.04 over the function v(t) dt., with v(t) being 11.31-10.9t. This equals ca. 5.87.

As you can see, your point can be disproved using basic mathematics and about 15 minutes of research and calculating.

As I am not a motherspeaker, I would appreciate any effort to help me making this point more understandable.

Let's break the motion of any cart into forces. There is the force applied to the cart from the powered rails, lets called it applied force (F_{a}), next there is the force of friction, which opposes motion of an object, lets call this force of friction (F_{f}). Next there is the force of gravity, (F_{g}). Now lets make an equation. We want F_{a }to be greater than F_{g} (it's component along the axis of the rail, which is F_{g}sin(theta) where theta is the angle of slope, in minecraft this will be 45 or 90. There is also the frictional force, which is the coefficient of friction (μ) multiplied by the normal force, which is F_{g}cos(theta). Thus we get the equation F_{a} >= F_{g}sin(theta) + μF_{g}cos(theta). Essentially if the left is greater than the right, the cart will accelerate, forwards, if right is greater it will accelerate backwards, and if it is balanced it will keep a constant velocity. Now lets imagine the slope is 90 degrees (vertical), which means we plug 90 into theta. sin(90) = 1 and cos(90) = 0 therefore the equation simplifies to F_{a} >= F_{g} , which becomes m*a_{p} >= m*a_{g} , which is mass independent, so a_{p} >= a_{g} where a_{p} is the acceleration from the powered rail, and a_{g} is the acceleration due to gravity. So, lets find out what each acceleration is. Since I couldn't find any information online about how a powered rail accelerates a minecart I did my own testing using redstone timers and detector rails. What I found is that a minecarts have top speeds of 8m/s, and they only need two powered rails to achieve that speed. With one powered rail it would take the cart 1.75 seconds to travel 8 meters, this gives a velocity of 4.57143, keep in mind that this number is the average velocity over the course of 8 meters. Using kinematics equations we can find the acceleration of the cart while it is on the powered rail. I will use the equation V_{f}^{2 }= V_{i}^{2 }+ 2ad, where d is 1m (length of powered rail), a is what we are solving for, V_{f} is the final velocity (4.57143m/s), and V_{i} is the initial velocity (0m/s) plug those numbers in and you get an acceleration of 10.449m/s^{2} Great, now we have the acceleration a minecart will experience when on a powered rail. Now lets compare that to the gravitational acceleration. According to this http://minecraft.gamepedia.com/Entity#Motion_of_entities The acceleration of minecarts and boats is 16m/s^{2} which is greater than than the acceleration due to a powered rail. the net force on an object is the sum of all the forces on an object, so in out case F_{net} = F_{a} + (-F_{g}) so, the net acceleration on this cart is going to be -5.55m/s^{2}. So, even with power rails going all along the vertical you will a max height, I will use Vf2 = Vi2 + 2ad since it does not involve time, from this we get 5.76577m, or just under 6 blocks before you begin to reverse

Edit: Tried to explain it so anyone reading this could understand, and I I could have done this other ways, but whatever, it worked.

I fail to see that, in-fact the math proves the opposite.

I think it would be better for something like a "chain rail" which would pull the minecart up the incline similar to a real roller coaster. As for upside down rails they could have additional bits which would "hold" the cart, similar to a roller coaster.
