# Newton's 100 ~ The Diamond Mobile

## Newtons First Law

First Law : every object in a state of motion tends to remain in motion unless an external force is applied on it.

My vehicle uses this law by winding up the rubber band creating force and releasing the axel the rubber band forced the axel to turn letting the vehicle move.

## Newtons Second Law

The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector.

My vehicle uses this law by winding up the rubber band a certain amount of times to create an equal force with the mass.

## Newtons Third Law

For every action there is an equal and opposite reaction.

My vehicle uses this law by releasing the wound up axel letting the car move.

## Reflection

At the begging of the Newton's 100 project Amy and I decided to use cardboard as the wheels and a shoe box as the car and skewers as the axles. To make the car go one meter we would have to rotate a rubber band around the skewers a few times and make the car go a full meter. 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 and use pencils as the axels. It was a success. Amy and I named our car The Diamond Mobile we ended up going to finals but then lost due loose wheels. The Newton's 100 project was a great experience.
