  By applying varying forces
• Hooke's Law can be expressed mathematically as $F =$$k \times x$
• What does the spring constant measure in Hooke's Law?

  Stiffness of the spring
• The limit beyond which Hooke's Law no longer applies is called the elastic

  1️⃣ Apply a known force to the spring

  2️⃣ Measure the extension of the spring

  3️⃣ Calculate the spring constant using $k =$$F / x$
• What is the unit of the spring constant in Hooke's Law?

  N/m
• Match the aspect of Hooke's Law with its description:

  Proportionality ↔️ Force and extension are directly related

  Elastic Limit ↔️ Maximum force before permanent deformation

  Spring Constant ↔️ Measures the stiffness of the spring
• The force needed to extend a spring is inversely proportional to its extension.

  False
• The spring constant in Hooke's Law is measured in N/m.
• What is the unit of measurement for force in Hooke's Law?

  Newtons (N)
• Hooke's Law applies regardless of whether the elastic limit is exceeded.

  False
• The proportionality constant in Hooke's Law is called the spring constant.
• What does the spring constant (k) measure?

  The stiffness of the spring
• The spring constant is the proportionality constant in Hooke's Law, representing the stiffness of a spring.
• Match the spring type with its stiffness and spring constant:

  Stiff Spring ↔️ Very Stiff, 500 N/m

  Regular Spring ↔️ Medium Stiff, 250 N/m

  Flexible Spring ↔️ Very Flexible, 100 N/m
• Hooke's Law states that force is proportional to extension or compression, as long as the elastic limit is not exceeded.
