Lab 4: Function Monday 6:20-8:10pm Abstract The objective of this lab is to find the uncertainty by using statistical analysis. The percentage of one standard mean value and two standard mean value are 75% and 95% which is very close to the theoretical value. Also the slopes of these f s v. f n and f k v. f n graphs also show that µ k =0.174 and µ k = 0.232 which is also within the value that was mathematically calculated in part 1.

Objective The objective of this lab is to use a statistical analysis to determine a final measured value with proper uncertainty. Procedure The weighted block was pulled, the force senor and the computer was used to measure the tension of the pulling string during the pull. Result Part 1 µ s = 0.232±0.003 µ k = 0.169±0.002 Part 2 f s ±σ = 75% f s ±2σ = 100% f k ±σ = 75% f k ±2σ = 95% Data analysis Part 1 = = . .
