Investigating Springs

• Elastic potential energy = 0.5 x spring constant x extension^2
• A pulley can be used to make sure the string doesnt rub again the wood.

  
• SPRING PRACTICAL

  
  

  1) Clamp and mark the bottom of spring

  2) Measure length of original spring, use a ruler clamped to stand.

  3) Add mass to spring.

  4) Record new length and mass.

  5) Repeat Until you use all masses.
