# Newton's 100 ~The Diamond Mobile

## Newton's First Law

1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. My vehicle uses this law by winding up the rubber band creating force then releasing the abel the rubber band forces the axel to turn letting the vehicle move.

## Newton's Second law

2. The relationship between an object's 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. My vehicle used this law by winding the rubber band. The rubber band clipped on one end and tied to an axel on the other. We had to wind our rubber band a certain amount of times to create an equal force of mass for the car to work.

## Newton's Third Law

3. For every action there is an equal and opposite reaction. My vehicle used the third law by the force built up on the rubber band and had an equal force upon it.

## Reflection

The Newton&apos;s 100 project was an exciting experience and also very difficult. Bella and I thought of a idea to use cardboard as the wheels and a shoe box as the car and pencils as the axles. To make the car go one hundred centimeters you would have to rotate a rubber band around the pencils a few times and make the car go a full hundred centimeters. Our car was going slow with the card board we decided to use Cd's and hot glue two of them to each side of foam. It was a success. Bella and I named our car The Diamond Mobile we ended up going to finals but then lost I had a great experience working on Newton;s 100 project. I learned about Newton&apos;s three laws and how they work.
