Score: 51Sarah Young says: Great job on this video! I really liked the style- it was more interesting than some others and getting to watch examples like Sammy was really helpful. One thing I think you could have expanded on was that friction force is essentially normal force, which is why it rises to the occasion. You had a really great opportunity to do this when you were discussing how the static friction force rises as you apply more force on Sammy, and if you had discussed normal force and what the two surfaces look like zoomed up really close it would have helped explain friction even more. Other than that great job!
