Stretching spring investigation

• Hypothesis: I think that the more weights that are put on the Spring, the
• Method

  1. Set up apparatus as shown

  2. Measure spring length without any mass and record this in the first space in your table - this is your initial spring length (without any mass stretching it)

  3. Add your first mass and measure the length of the spring with the mass

  4. Calculate the extension

  5. Repeat this with other masses

  6. Draw a graph of your results
• Results

  • Force (N)
  • Length (cm)
  • Extension (cm)
• Did you have any anomalies?
• Why do you think this was?
