Newton's 100~ The Marshmallow

Newton's 1st Law

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. this law applied to my car because wen i wound up the rubber band which was connected to my axles and whenwe let it go it moved.

Newtins 2nd Law

II. The relationship between an object and mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. This law applied to my car because without the force or the mass my car wouldn't go from destination point A to destination point B?

Newton's 3rd Law

lll. For every action there is an equal and opposite reaction. This law applied to my car because when I wind up the wheels and let go of them the right amount of mass and force would make my car accelerate. (F=MA)

At first my car moved 700 meters. We worked on speed and tried to make our wheels stop whobling. When i winded my car up and let it go it was fast. In the end my car was awesome.Trial l. 215 cm/sTrial ll. 161.5 cm/sTrial lll 174 cm/s

Reflection

At first my car was perfect and it went 7 meters. It started to get worse because Cole and I changed the rubber bands.It was a very difficult but fun project. We changed our vehicle design a lot. It was either two big of a box or wasn't heavy enough. When we finally found the perfect box we started to build it. We had a great rubber band,great wheels,great axles,and a great idea. Our car was built in a day and went 7 meters! It felt great for our car to go more than a meter one day before our deadline.It was an amazing expirence and I was happy i had an oppurtunity to build a car.
