Splatter Car... So Far

Backround Information
This post has all the information that may be helpful to know about how the car works!
All information was taken from our textbook or Ms. Orzech's PowerPoints.
Newton's 1st Law (Inertia):
An object at rest will stay at rest, an object in motion will stay in motion unless acted upon by an outside force.
Newton's 2nd Law:
Net Force equals mass times acceleration. (N=ma)
Newton's Third Law:
For every action there is an equal and opposite reaction
Acceleration:
The rate at which velocity changes
force / mass = acceleration
Mass:
The amount of matter in an object
force / acceleration = mass
Friction:
When two surfaces rub together
Acts in a direction opposite to the object's direction of motion
Strength of friction depends on two factors: 1) Type of surface 2) How hard the surfaces push together
Rolling Friction:
This is the friction our car has with the floor! It is due to... you guessed it! When an object rolls over a surface
Momentum:
Momentum is the quantity of motion
Momentum= mass x velocity (P = ma)
Unit= kilogram-meters per second (kg x m per s) in a direction
The smaller the mass, the smaller the momentum, so our car with has to be a decent size.
Law of Conservation of Momentum:
The total momentum of the objects that interact does not change

Balloon Car Project Intro
This Balloon Car Project is, of course, one of the most singularly important things that we will accomplish within this lifetime. The formula is simple: balloon + car = awesome project. Now why is this project at the top of the project chart? Because it incorporates science - without formulas or a lab report. This project is about Physical Science in action!
