## Homework Statement

Design and complete an investigation to determine how the following factors affect the force of friction:

- weight
- surface are
- speed

## Homework Equations

The magnitude of the force that is provided by an elastic band is directly related to the distance the elastic band is stretched.

## The Attempt at a Solution

Well I am kind of clueless. I thought I could use some tissue boxes, with different weight, surface area to do the first 2. Then I could just increase the speed on the third one..

**What I am confused about**

I am not sure what really to do.. So the amount of how much the elastic band is stretched will show me how much force I put in.. How do I convert that force into N? Also not sure how really to do the experiment.. Maybe if I become clear about the elastic band thing then I'll understand some more.. Because right now I don't understand how I could prove how the previously mentioned factors affect the force of friction.
