Lab 10 - Hooke’s Law using Computer Simulation
(Taken from Phet)
In this activity the learning objectives are:
● Measuring extension and force using a program
● Recording and explaining data for springs using Hooke’s law
● Recording and explaining data for springs connected in ‘parallel’ a
angements
Extra Challenge:
● Describe and explain the relationship between elastic energy stored and extension
in a spring. OR set up an investigation of your own
The website you need for this is Phet Simulations (University of Colorado)

On opening the program, click on INTRO
EXPT 1 Using one spring of force constant 200N/m
Use the program to record data in your table below- you will need to click on ‘values’ to take
measurements of displacement (extension) from equili
ium.
Force Applied (N) Extension (m)
1. Describe the pattern in your results. How is the force applied related to the
extension? Give examples from the data you have taken

2. Sketch the a
angement of the spring as shown on the screen.
Show the direction of the applied force on the spring AND the spring force on your diagram.
Use colour to tell them apart.

EXPT 2 Using two springs of force constant 200N/m in parallel (side by side)
On the main menu go to SYSTEMS.
Vary the applied force and record the extension or displacement from equili
ium.
NOTE: Use the same force values you used in Experiment 1.
Force Applied (N) Extension (m)
4 Explain the main difference in the extension produced by this ‘spring system’ compared to
the system in Expt 1.
