RP: how forces affect the extension of a spring

• What is the main purpose of forces in relation to objects?

  Forces are responsible for changing the motion of objects.
• What happens to the shape of an object when more than one force is present?

  The shape of an object can also be changed.
• What is the aim of the experiment investigating the relationship between force and extension for a spring?

  • To investigate the relationship between force and extension for a spring.
• What is the first step in the method for investigating the relationship between force and extension for a spring?

  Secure a clamp stand to the bench using a G-clamp or a large mass on the base.
• What should be used to attach two clamps to the clamp stand?

  Bosses should be used to attach two clamps to the clamp stand.
• How should the ruler be adjusted when setting up the experiment?

  The ruler should be adjusted so that it is vertical, with its zero level with the top of the spring.
• What is the unloaded length of the spring measured for?

  The unloaded length of the spring is measured before any weights are added.
• What weight is used for the first measurement in the experiment?

  A 100 g slotted mass carrier, weighing 0.98 newtons (N), is used for the first measurement.
• What should be done after hanging the first weight from the spring?

  Measure and record the new length of the spring.
• How many times should the process of adding weight and measuring the spring be repeated?

  The process should be repeated until a total of 1,000 g is added.
• What should be included in the results table for the experiment?

  • Force (N)
  • Length (mm)
  • Extension (mm)
• How is the extension calculated for each result?

  Extension is calculated as extension = length - unloaded length.
• What should be plotted on the graph in the analysis section?

  A line graph with extension on the vertical axis and force on the horizontal axis should be plotted.
• What should be identified from the graph regarding the extension of the spring?

  The range of force over which the extension of the spring is directly proportional to the weight hanging from it should be identified.
• What is one way to improve the accuracy of length measurements in the experiment?

  • Keep the ruler vertical.
  • Use a digital measuring device.
  • Take multiple measurements and average them.
• What are the hazards and control measures in the experiment?

  Hazards:

  • Equipment falling off table
  • Sharp end of the spring recoiling
  • Masses falling to the floor if the spring fails

  
  

  Control measures:

  • Use a G-clamp to secure the stand.
  • Wear eye protection.
  • Gently lower load onto spring and step back.
• What is the consequence of equipment falling off the table?

  Heavy objects falling on feet can cause bruises or fractures.
• What should be done to prevent damage to eyes when using the spring?

  Wear eye protection to prevent damage to eyes.
• What is the consequence of the sharp end of the spring recoiling if it breaks?

  It can cause damage to eyes or cuts to skin.
• What should be done if the spring fails during the experiment?

  Gently lower the load onto the spring and step back to prevent injury.
