On Friday's class we did a lab on friction, the equipment that we used for the lab are:

• 5 bricks
• a dynamics cart
• string
• brown wrapping paper
• wax paper
• sand paper
• plastic wrap
• 2 spring scales
• masking tape

Basically we measured the force of friction through many procedures in the lab.

Reminders!

1. Finish the questions on the last page
2. Create a graph for table 9-6 (Data and Observations)

Finally the next scribe will be.... Awot!
