1. Title: Friction!
2. Purpose: To measure how much friction is created when a block of wood is dragged across different surfaces.
3. Background: Friction is wasted energy.
4. Procedure: Hook the block of wood to the duel range force sensor. Then gently pull the utility handle. The data is collected with the nxt and sent to the computer. Where you can use the data to make a graph and visually see how much friction is created on each surface.
5. Materials:
Block of wood
Duel range force sensor
Nxt
Computer desk
Carpet/ fabric surface
