Friction Lab 3.2.12
Part 2: Starting Friction
1. What is friction?
The resistance of one object going over another.
2. What causes friction?
Roughness of the object that slows down an object in motion.
3. Record your data in the table below as you conduct the activity.

4. When you moved the block across the table, was the force of friction acting against the block greater or less than the force you exerted on the block. How do you know?
The force exerted on the block against the sand paper was greater because of the recordings. Without the sandpaper, it only took an average of 3 N to move the block. However, it took 5 N to move the block across the sandpaper. Therefore, more force was used to move the block over the sandpaper.
