1. The problem statement, all variables and given/known data Errors that might arise through this experiment: A puck upon a air table which makes certain dots with a specific length in between each of them for a 50 g mass and a 150 g mass, we need to find the acceleration, which i did and the coefficient of the friction that they both might face. However the friction r not the same.. when they r supposed to be due to my teacher. Anyhow.. what might be the errors in this lab? 3. The attempt at a solution 1) gravity might vary from places 2) ruler lengths might vary 3) mass of string not taken in 4) friction of string and pulley ignored 5) uncertainty of masses 6)the unleveled surface 7)air resistance 8) changes in the temperature or the humidity.
