//__ Title __//

How surfaces with different materials accelerate down an inclined plane against the force of friction

//__ Objective __//

The purpose of our experiment is to explore how friction boxes with surfaces containing three different materials; plastic, felt, and cork with identical masses affect the forces acting upon the object and therefore the acceleration. We predict that the friction box with the plastic surface will have the fastest acceleration due to the fact that the force of friction will be weaker with the plastic material. Our second prediction is that the friction box with the cork material will have the least acceleration because the force of friction will be stronger against the felt material.

//__ Procedure __//


 * First Step: ** Gather three friction blocks each with different surfaces (plastic, felt, and cork)
 * Second Step: ** Collect 125, 250, and 500 gram weights
 * Third Step: ** Pile up 10 textbooks and place one side of the ramp on top of the textbooks to create an incline
 * Fourth Step: ** Attach motion sensor to GLX and place the sensor at the top of the ramp
 * Fifth Step: ** Place plastic box with the 125 gram weight inside and let it slide down the inclined ramp, repeat this for each of the different boxes (attach motion sensor to GLX and place the sensor at the top of the ramp). Record the results
 * Sixth Step: ** Place plastic box with the 250 gram weight inside and let it slide down the inclined ramp, repeat this for each of the different boxes (attach motion sensor to GLX and place the sensor at the top of the ramp). Record the results
 * Seventh Step: ** Place plastic box with the 500 gram weight inside and let it slide down the inclined ramp, repeat this for each of the different boxes (attach motion sensor to GLX and place the sensor at the top of the ramp). Record the results
 * Eighth Step: ** Graph and compare the results to discover which material resists friction the least and which material resists friction the most.
