Model Aeroplanes

I need Help ASAP!!!!!!!!?

The lab is about, "How is the Stretch of the Rubber Band related to the Distance Flown” when flying a paper airplane using a rubber band as its propulsion?". Ive been Homeschool for years and now that im in regular school, im soo confused on everything. I dont even know, what to write for the Hypothesis, all i know is the main point for the Lab is too. Relate it to Potential, Kinetic energy.

wat does the question say?
how far is the stretch related to the distance?
so....
u have a rubber band... a paper clip... a piece of paper and a metric ruler....

the hypothesis is the educated guess...
my hypothesis is that the harder u pull, the longer the rubber band
the longer the rubber band, the farther it goes.

this is how i would demonstrate this
procedure....
lay metric ruler on piece of paper....
then i lay rubber band down on piece of paper
measure the rubber band
then pull the rubber band one centimeter
then measure the distance that it flew
then pull the rubber band two centimeters
then measure the distance it flew
then pull the rubber band three centimeters
then measure the distance it flew

your conclusion should be that the farther you pull the rubber band the more energy it has to fly
so... the potential energy and the kinetic energy part

Energy is the Ability To Do Work

There are two types of energy -- stored (potential) energy and working (kinetic) energy.

Potential energy is energy that is stored in an object. If you stretch a rubber band, you will give it potential energy. As the rubber band is released, potential energy is changed to motion.

Kinetic energy is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy.

Potential energy is converted into kinetic energy. Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been converted into kinetic energy so that it now has its maximum kinetic energy.

Potential and Kinetic Energy
All energy is either potential or kinetic.

Potential Energy
Potential energy is energy that is in a stored form. It isn't being used at the moment, but is waiting to do work. Think about a boulder sitting on top of a hill. Just sitting there, the boulder isn't doing anything. But because it is sitting on top of a hill, it has the potential to roll down and do some damage to a car or building below. The energy is stored in that rock because of its size (mass) and the distance it will travel once it starts rolling.

Kinetic Energy
Kinetic energy is energy that is in motion. This energy is performing work. Legs are pumping bicycle pedals. Coal is running generators. Lightning is snapping trees.

so relating this to the lab
the farther u pull the rubber band the more potential energy in has
the more potential energy it has the more kinetic energy it will have....

i really hope this helps alot...
i dont know about u but i think u should read the book ...
