Physics IA 0907 Practical

Extracts from this document...

Introduction

Name:Anh Linh

Class: 5Y

EXPERIMENT 0907:

Finding the Mass of a Metre Rule using the Principle of Moment

Aim:

In this experiment you will use the principle of moments, together with the idea of the centre of gravity. To find the mass of a metre rule.

Data Collection, Processing and Presentation:

 m1/kg0.001m d1/m0.001m d2/m0.001 d2/d10.001

Equation for uncertainty in :

 m1/kg0.001m d2/d10.001 m2=m1d2/d1 Uncertainty in m2 0.050 1.941 0.0501.941=0.097 8.9110

Conclusion

Beside all the other errors, there’re always an uncertainty error existed.

Suggest ways in which the accuracy of the measurement taken could be improved.

Switch of the air-conditioners in the physics labs. Close all the windows.

Try to take the pivot point when the rule is balance which means almost parallel to the table surface so we can have the best record value.

Check the string tie at one end of the rule so we can make sure that the clockwise moment is correct.
