To Chris You have a logical fallacy, You say that since A follows one law then B must also follow the law in the same fashion. Try to avoid using force and energy interchangeably, they aren't synonymous.However think about this, Energy, which can be used synonymously with heat, does not need an...

Actually it reuires much more complex programing then using a single motor and chain. For that style you have to program the motors to run in opposite and be synchronized. It will require programming for two motors. Since it has two motors it is also more expensive. My idea requires the...

To Ank Well the second way would, but if he is just testing stability in the process of turning, it would work. The first way is similar to your B737 idea but it only requires the programing and control of one motor. They use hydrolics on planes because you can get more force and they use a...

Actually it would be quite easy to do. I'm assuming you have access to motors. a small motor with a sprocket on the drive shaft and a chain attached to a sprocket on the wheels shaft and you could have it steer either direction you wanted. (this requires some programming if you want to control...

You could put a paper clip on the back wheel, It would jam the wheel into a stop position, when the canister drops, it hits a lever that lifts the paper clip up releasing the wheel. I wish i could draw a diagram. It would work similar to a caliper brake on a bicycle except instead of releasing...

The best style release mechanism could also change for how you are using the rubber band. In essence how are you using the rubber band specifically?

Sorry if this is common knowledge, but what in the heck is a demon, I'm assuming not a minion of hell!

Which eventually means that the entire universe will reach the same temperature! (hopefully in the upper 80's for comfort :P ) Hopefully this makes sense to you pinestone. Nothing has to have an opposite but rather a lack thereof, so that it eventually reaches the same temperature...

a car traveling in reverse is still a car

Agreeing with Dave And that's what the 2nd law is saying, that all systems are trying to move towards no spontaneous reactions, that is the function of light. When particles reach to high of an energy level they drop their electrons to a lower shell by releasing a photon. That photon travels...

Last summer I spent a few days at RIT taking some seminars on engineering and what different courses would be like, one of the professors was demonstrating some of the materials we would get to use and he produced a an object consiting of two metal plates sandwiching some other sort of material...

2nd Law of what (thermodynamics, Newtons laws, us constitution) there are a whole lot of laws out there? As for the motion of photons, they are moving everywhere around us, sometimes towards us sometimes away, we just don't see it until it reflects back to us. Say your standing with the sun...

Also, when doing equations, acceleration due to gravity is a negative number wether your using -9.8 m/s2 or -32 ft/s2 Gravity never acts in a positive direction so you'll get funky numbers if you plug it in as a positive value!

Leozeo- In an equation like this you never consider the initial velocity zero, the initial velocity is taken after the force has acted upon the object. Without the force the ball won't move You can see this in the equation I wrote, If you plugged in zero, then the entire equation is...

That won't necesarilly work. While salt peter will work as an oxidizer and allow you to burn the sugar easily, you won't get the pressure needed for take off, essentially you'll just burn your rocket down. When burning youll either need to keep the fuel in a small space and have the...
