We are trying to find out what factors affect frictions. Friction is the force that opposes motion, or makes it difficult an object to move across a surface. The amount of friction depends on the surface type and the force pressing two objects together. I am going to research three factors: ?óÔé¼?ó Different surfaces ?óÔé¼?ó Area of contact ?óÔé¼?ó If the surface is wet For our preliminary work we used a block of wood with a hook in the end of it. We attached a Newton metre to measure the amount of friction;...
could have affected this as I have talked about earlier. I think that my results back up my conclusion quite well.

My method worked very well I did not experience any real problems and found working by step by step method straight forward.

To develop my experiment more I could;

?óÔé¼?ó Do this experiment several more times.

?óÔé¼?ó Do the same experiment but use several different surfaces, smooth table, rough sandpaper or a shiny black bag.

This experiment has tested many theory's and has provide me with a basic level of understanding.
