    • What does kk represent in Hooke's Law?

      Spring constant (N/m)
    • How is the spring constant kk calculated if a spring extends 0.2m under a 5N weight?

      k=k =25 N/m 25 \text{ N/m}
    • What does the equipment at the bottom of the image measure?
      Masses
    • What happens when you stretch a spring further according to Hooke's Law?
      It pulls back harder
    • What does Hooke's Law state about the force applied to a spring?
      It is directly proportional to its extension
    • How does the force required to stretch a spring twice as far compare to the original force?
      • The force required to stretch the spring twice as far is 2 times the original force
    • What is the relationship between the force required to stretch a spring and the amount it is stretched according to Hooke's Law?
      • The force required is proportional to the amount the spring is stretched
      • The spring constant k determines this relationship
    • How does the extension of a spring relate to the force applied according to Hooke's Law?
      More extension means more force applied
    • How is the spring's extension measured?
      Using a ruler against a fixed point
    • What is Hooke's Law?
      F = -kx
    • What does the spring constant kk represent?

      Force needed to stretch the spring by 1 meter
    • How can the relationship described by Hooke's Law be expressed mathematically?
      As a proportionality equation
    • What does a higher spring constant kk indicate about a spring?

      It requires more force to stretch
    • What is the unit of the spring constant kk?

      Newton per meter (N/m)
    • What is the spring constant of this graph?
      50 N/m
    • If a spring has a spring constant k=k =25N/m 25 N/m, how much force is needed to stretch it by 1 meter?

      25 N
    • According to the image, what is the force when the extension is 0.04 m?
      2 N
    • According to the image, what is the extension when the force is 4 N?
      0.08 m
    • What creates the force applied to the spring in Hooke's Law?
      The weights (masses) applied
    • What type of relationship exists between force and extension?
      Linear relationship
    • What happens to the relationship F=F =kx kx when the elastic limit is exceeded?

      It no longer applies
    • What does the spring constant k represent in Hooke's Law?
      The spring constant
    • What is the name of the piece of equipment on the right side of the image?
      Ruler
    • What are the variables in Hooke's Law F=F =kx kx?

      • FF: Force (N)
      • xx: Extension (m)
      • kk: Spring constant (N/m)
    • What is the name of the equipment at the top of the image?
      Spring
    • What does the spring constant kk determine?

      The steepness of the line
    • What happens to extension with each additional unit of force applied?
      Extension increases by a constant amount
    • What does FF represent in Hooke's Law?

      Force (N)
    • What is Hooke's Law?
      It relates force to spring displacement
    • What does a steeper line on the graph indicate about the spring?
      The spring is stiffer
    • How is the spring constant kk calculated from a weight and extension?

      By dividing force by extension
    • If a spring has a spring constant of k=k =5 N/m 5 \text{ N/m}, what force is required to stretch it x=x =2 m 2 \text{ m}?

      F=F =kx= -kx =52= -5 \cdot 2 =10 N -10 \text{ N}
    • Why is Hooke's Law not true forever?
      Because every spring has an elastic limit
    • What extension did the spring experience with the 5N weight?
      0.2 m
    • What does xx represent in Hooke's Law?

      Extension (m)
    • What does the graph represent, and what information can be obtained from it?
