zakstillwell Random Crap:

because i cant post to random crap, i will just post it all here on this post.

Topic: Physics lesson for you guys!

Newton’s Laws in the “Balloon Car Project”
Newton’s 1st law of motion states that an object in motion tends to stay in motion. After the car began to move you might think that it would continue perpetually. However, the law also states it will only do so if an outside force, or an un-balanced force does not affect it. So really, how well the wheels spun decided how far the car went. The ground acts as an outside force in this instance, as are the wheels. The balloon pushes the car forward. The wheels rolling on the axels cause friction. The ground the wheels touch causes friction. The best way to make a balloon car travel the farthest distance therefore is to reduce friction on the axels to wheels, and wheels to ground as much as possible.

Newton’s 2nd law states that acceleration is decided by the mass of the object as well as the force applied to it. A good example is if you were at a shopping mall and had a cart full of designer clothes, it is harder to push, but keeps going once started because of increased inertia. However if you are just messing around with a half full cart with your friends, and you throw it out in front of you, 1/2 mass equals 2/1 acceleration. It will therefore stop sooner because of decreased inertia. The same concept applies with the balloon car because if it is very heavy, it has a large mass. If it has a large mass it is harder to get moving and to stop. Right in between however, is a point where the car can get moving and also has enough mass to ride on the force of inertia, even after the balloon stops pushing. The law also states that the direction of acceleration is the same as the direction of the force applied. By making the wheels point straight forward and making the balloon push that same direction as well, all energy is moving either forward, up, or down. Forward energy is lost in moving the car forward. Upward energy is lost due to air friction. And downward energy is lost in the ground.

Newton’s 3rd law states all actions in the universe have an equal and opposite reaction. When the balloon pushes air one way, the car goes the opposite. By increasing the air pressure coming out of the balloon, it would thereby create more force and push the car faster, with more force. The air pressure can be easily increased though. It would simply involve either a balloon that is harder to blow up (tighter elastic) or by finding the right size hole that the air comes out of. It is hard to say how big for I do not know the exact bollon being used, or the mass of the car. Because acceleration occurs in the same direction as the force applied, we now can build a perfect hypothesis of the best way to make a balloon car work by using all three laws like this:
Newton’s 1st: Low friction axels, minimal traction wheels, so there is less of an outside force, or an “unbalanced” force preventing the car from building momentum. Newton’s 2nd: A low mass car, which is lightweight, with straight wheels and a strong mass of air pushing it. This way enough inertia can be built up. Newton’s 3rd: A tighter, higher-powered balloon, pointed the opposite direction of where the car is intended to be heading. This way the opposite reaction of the air coming out will be used more in moving the car towards the finish than dragging it along the floor.

First post = tl;dr. Second post = i read that 2 days ago -_- ur not up to date bud...

Tldr any of that.. 1.4 is out btw, WOLVES FTW!
