= TITLE: __Static Friction and Weight__ =

= OBJECTIVE: = ===The goal of our experiment is to find the static force of friction on boxes with different surfaces when a 500g weight is placed inside each box and when a 1000g weight is placed inside each box. The different surfaces on the boxes that we are testing are cork, plastic, and felt. We are going to test the static force of friction by pulling the box from rest and finding the force using the GLX. One challenge we might face is using the exact same amount of pulling force for each test run. We predict that the greater the weight the more friction there will be. We also predict that the cork will have the most friction, followed by the felt and then the plastic will have the least friction.=== = =

= PROCEDURE: =

Procedure:

 * 1) ===Weight each of the friction boxes and record the mass. You will use the mass of each to calculate the static force of friction (Fs)===
 * 2) ===Attach the force sensor the GLX.===
 * 3) ===Use the hook on the force sensor to attach to one of the friction boxes and put the 500g weight in the box.===
 * 4) ===Turn to force sensor on and gently pull it until it moves. Once it begins to move, stop and record the force that you applied by pulling the box.===
 * 5) ===Replace the 500g weight with the 1000g weight and use the force sensor to detect the force applied before the box starts to move.===
 * 6) ===Repeat steps 3-5 for each of the friction boxes===
 * 7) ===Compare the static friction of each the boxes with the different weight components===
