Elasticity, Spring Constanr and Hookes Law

• What are the different types of deformation

  Elastic and inelastic deformation
• 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 an object that does not return to its original shape?

  Inelastic deformation
• What is extension in the context of springs?

  Increasing length of a spring when stretched
• How does the weight of a mass affect a spring?

  It pulls on the spring, increasing its length
• What does the natural length of a spring refer to?

  The length of the spring without any forces
• What is the relationship between force and extension in a spring?

  They are directly proportional
• What does the symbol 'k' represent in the force-extension equation?

  The spring constant
• What is the equation for force in relation to spring constant and extension?

  $f =$$ke$
• What does a higher spring constant indicate?

  Stiffer material requiring more force
• What does a straight line graph of force against extension indicate?

  Force and extension are directly proportional
• What is the elastic limit in the context of Hooke's Law?

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

  It may undergo inelastic deformation
• What are the key concepts related to elasticity discussed in the video?

  • Types of elasticity: elastic and inelastic
  • Spring constant: measures stiffness
  • Hooke's Law: force proportional to extension
  • Deformation types: elastic returns to shape, inelastic does not
  • Extension: length increase when stretched
• What factors affect the behavior of springs under force?

  • Mass applied to the spring
  • Spring constant (k)
  • Elastic limit of the material
  • Relationship between force and extension
