 * Research Question:** which surface will take the most of the force to travel?
 * How does surface and weight effect the size of the fiction force?**


 * Hypothesis**: if carpet has the most friction, then it will take to most force to pull, because carpet is a rough surface.


 * If the surface causes more friction, then the rough surface will take most of the force because rough surface take more friction to pull.**


 * Material:** You will be given three different surfaces, mass and a Newton meter.

1. Draw a Data Table to record the different types of surfaces to be tested and the force needed to pull the block at a constant speed. Note that this data table should be included under the //__Data and Calculation section__//.
 * Procedure:**
 * Part I**

2. Place 500 grams in the box with the surface to be tested.

3. Attach your newtonmeter to the block.

4. Using the newtonmeter, try and pull the block along the surface. __Note the force needed to pull the block at a constant speed and record in your Data Table.__

5. Repeat steps 2-4 for the other different surfaces.
