**Atwood machine**

background [prelab assignment (10 points) due at the begining of lab]

1. develop two methods using graphical analysis to estimate the value of g using the below materials. basis / rationale

purpose

using the graphical analysis,

describe the relationship between the acceleration of an object and __ of the two masses on opposite sides in the system

the difference in mass

the total mass

estimate the value of g

materials

photogate

different masses; string; pulley, ring stand

methods / data analysis

student design

**content of lab report** [25 points]

introduction -- basis of subsequent analysis; i.e. your prelab assignment [5 points]

using the graphical analysis, [15 points]

describe the relationship between the acceleration of an object and __ of the two masses on opposite sides in the system

the difference in mass

the total mass

estimate the value of g\

using the appropriate statistical test, compare the value of g using both graphical methods [5 points]
