Required Practical : Hooke's Law

• What is the method of the Hooke's Law?

  1. Measure starting length of spring using a ruler when no load is applied.
  2. Add a marker at the bottom of the spring to make reading more accurate
  3. Add a mass to spring, allow it to come to rest and measure the new length
  4. Calculate the extension(change in length)
  5. Repeat until you have at least 6 measurements
  6. Remember to use the same spring made of the same material if you repeat or compare readings
• This is how you can tell it is Elastic Potential Energy
