Hooks Law

• What is Hooke's Law?


  Hooke's Law describes how a spring or elastic object behaves when a force is applied, stating that the force needed to extend or compress a spring is directly proportional to that distance.
• What does it mean that force is directly proportional to extension in Hooke's Law?


  It means that if the force applied to a spring increases, the extension of the spring also increases in a linear manner.
• What are the key components of Hooke's Law?

  The key components are force (F), spring constant (k), extension or compression (x), and elastic limit.
• What is the unit of force in Hooke's Law?

  The unit of force is Newtons (N).
• What does the spring constant (k) measure?


  The spring constant measures the stiffness of the spring, measured in N/m.
• What is the elastic limit in Hooke's Law?

  The elastic limit is the point beyond which the spring won't return to its original shape.
• What is the mathematical equation of Hooke's Law?

  The equation is $F =$$k \cdot x$.
• What happens to the relationship between force and extension when the elastic limit is exceeded?

  The relationship becomes non-linear, and the material may undergo plastic deformation.
• What are some limitations of Hooke's Law?

  Limitations include the elastic limit, non-linear behavior at high forces, ideal spring assumptions, temperature effects, and plastic deformation.
• What are the key components of Hooke's Law and their relationships?


  - Force (F): Applied force in Newtons (N) - Spring constant (k): Stiffness in N/m - Extension (x): Change in length in meters (m) - Elastic limit: Point beyond which the spring won't return to original shape
• What are the limitations of Hooke's Law?

  - Only applies up to the elastic limit - Non-linear behavior at high forces - Assumes ideal springs - Doesn't account for temperature effects - Doesn't apply during plastic deformation
• Elastic deformation : After the elastic object or string is stretched it will go back to its original shape
• Inelastic deformation : After the object is stretched it cannot go back to its original shape
