Friction Blocks Lab

Friction Blocks Lab. Conclusion Questions. 1. Does it take more force to start an object sliding over a surface or to keep it sliding at a constant speed? 2. Which surfaces produced the largest frictional force? The smallest?

  1. Friction Blocks Lab

  2. Conclusion Questions • 1. Does it take more force to start an object sliding over a surface or to keep it sliding at a constant speed? • 2. Which surfaces produced the largest frictional force? The smallest? • 3. What factors influence the frictional force between sliding objects? • 4. Looking at your graph, does your data produce straight “best fit” lines? What does the slope of each line represent?

  3. 5. What is the normal force? How does it affect the frictional force? • 6. How did the frictional forces compare when you pulled the block horizontally and then at 30o? Which was higher? EXPLAIN WHY.
