5.3.1 Hooke's Law

• What does Hooke's Law state about the relationship between force and extension in a spring?

  Force is proportional to extension
• Match the variable in Hooke's Law with its unit:

  Force ↔️ Newton (N)

  Spring constant ↔️ Newton per meter (N/m)

  Extension/Compression ↔️ Meter (m)
• A higher spring constant indicates a stiffer spring.
• Hooke's Law is valid only within the spring's elastic limit
• What is the mathematical equation for Hooke's Law?

  $F =$$kx$
• Match the variable in Hooke's Law with its symbol:

  Force ↔️ F

  Spring constant ↔️ k

  Extension/Compression ↔️ x
• Beyond the elastic limit, a spring will return to its original shape when the force is removed.

  False
• What is the unit of the spring constant (k) in Hooke's Law?

  Newton per meter (N/m)
• The force applied to a spring is proportional to its extension or compression according to Hooke's Law.
• Match the variable with its correct unit in Hooke's Law:

  Force ↔️ Newton (N)

  Spring constant ↔️ Newton per meter (N/m)

  Extension/Compression ↔️ Meter (m)
• What does the spring constant (k) measure in Hooke's Law?

  Spring stiffness
• Hooke's Law states that the force required to extend a spring is proportional to its extension
• What happens to a spring if it is stretched beyond its elastic limit?

  It undergoes plastic deformation
• The spring constant in Hooke's Law acts as the constant of proportionality between force and extension.
• What type of spring is described by a high spring constant in Hooke's Law?

  Very stiff
• Hooke's Law is valid for all materials, regardless of their deformation type.

  False
