The Great Race!

I must say, this was one interesting project! It was fun, though at the same time a little irritating because every time I tested it, my car kept breaking down(I made it out of Lego Blocks). In the end, my car is finally intact. My Lego car represents Newton's Second Law of Motion, which is that both mass and acceleration affect the force of an object, which can be calculated by multiplying the mass by the acceleration of the object. Next, when the momentum changes, it is directly proportionally to the force acting on it. This is represented by my car, because I tried to add more mass to my car, which would lead to more acceleration, which would then lead to more force. This way, my car could possible go pretty far until friction stops the tires from rolling on the surface. As my car is built up of Lego Blocks, I tried to add more mass by adding extra Lego Blocks and a passenger. In the end, I had to remove the passenger because it kept falling out every time I tried to test the car! Hopefully, because of some of the extra mass I've added, it created more acceleration and force for my car to go fast as well as far. May the best person win!

Me too! Although it seems as though it doesn't even have to be tested- the longer my car sits in the house, the worse it gets, and I don't know why! :( It used to run so smoothly, but now it's a little more rough and doesn't go so far. Oh well. :)
