Mini Lab: Elasticity and Hooke's Law

Activity’s Topic         : Experiment of elasticity Hooke’s Law

Activity’s Aim           : Find the relation between force and ratio of the change in length

Tools and Materials    :

1.     Statif

2.    Hang load 50 gr

3.    Spiral spring

4.    Ruler

Procedure
1. Hang the spring in the statif like shown in the experiment design
2. Measure the spring's length using ruler as the original length (l0)
3. Note the result in the observation table
4. Hang the load on the string then measure the length as (l)
5. Note the result on the observation table
6. Repeat the 5th step by add one more load to complete the observation table

Observation Result

1. Note the observation’s result in the table below

Original stpring’s length (l0) m	Mass/ weight of load (F)	Change in length ∆l = ( l – l0 ) m	F / ∆l

               2. Draw the graph of applied force versus elongation.

              3.Based on the graph, determine the spring’s constant.

      4. Call the reasons that caused the observation failed.
