Safety Considerations

  • Wear goggles during this experiment in case the spring snaps
  • Stand up while carrying out the experiment making sure no feet are directly under the masses
  • Place a mat or a soft material below the masses to prevent any damage in case they fall
  • Use a G clamp to secure the clamp stand to the desk so that the clamp and masses do not fall over
    • As well as this, place each mass carefully on the hanger and do not pull the spring too hard that it breaks or pulls the apparatus over
