• What does the term 'spring constant' refer to?

  It measures stiffness of a spring
• What is Hooke's Law?

  Force is proportional to extension
• What happens when a force is applied to an object?

  It can compress, stretch, or bend
• Which object is easiest to observe elasticity with?

  A spring
• What is the difference between elastic and inelastic deformation?

  Elastic returns to original shape; inelastic does not
• What is the term for the increasing length of a spring when stretched?

  Extension
• What force acts on a spring due to its own mass?

  Weight
• What happens to the natural length of a spring due to its weight?

  It becomes shorter than its actual length
• What does the solid support do when a mass is added to a spring?

  Exerts an equal but opposite force upwards
• How does extension relate to force applied to a spring?

  Extension increases proportionally with force
• What is the equation that relates force and extension?

  f = ke
• What does the spring constant 'k' indicate?

  Stiffness of the spring in N/m
• What does a higher spring constant indicate?

  Stiffer material requiring more force
• What does a graph of force against extension show?

  Direct proportionality between force and extension
• What is the significance of the elastic limit?

  Point where Hooke's Law no longer applies
• What happens to an object beyond its elastic limit?

  It may undergo inelastic deformation
• How do you measure the extension of a spring?

  1. Hang the spring from a solid support.
  2. Add a downward force (mass) to the spring.
  3. Measure the change in length from the natural length.
