Worksheet Hooke's Law Grade 11

Investigating Springs

1.  Purpose :

To study Hooke’s Law

2.  Apparatus :

3.  Theory (Made by you)

4.  Procedures

Use weight to stretch a spring, and then plot a graph to show the pattern of your results.

1.      Select a spring

2.      Fix the upper end of the spring rigidly in a clamp.

3.      Position a ruler next to the spring so that you can measure the complete length of the spring.

4.      Measure the unextended length of spring.

5.      Prepare a table for your result.

6.      Record your results in your table as you go along.

7.      Attach a weight hanger to the lower end of the spring. Measure its new length.

8.      Carefully add weights to the hanger, one at a time, measuring the length of the sprig each time.

9.      Once you have a complete set of results, calculate the values of the extension of the spring.

10.  Plot a graph of extension (y-axis) against load (x-axis) and comment on its shape.

5.     Data Record

mass (gr)	Length (cm)	Extension (cm)

6                                                    Table of data for plot of Force vs. Elongation

Load (Force) /N	Extension /m

Task

7

        Plot graph Force vs Elongation (in Excel)

8     Give comment on its shape.
