Elastic Potential Energy

• What is the first equation related to elasticity mentioned in the video?

  F = ke
• What does the variable K represent in the equation F = ke?

  Spring constant specific to each object
• What does a lower spring constant indicate about an object?

  It is more elastic and easier to stretch
• What does a higher spring constant indicate about an object?

  It is stiffer and harder to stretch
• What is the second equation related to elastic potential energy?

  Elastic potential energy = $\frac{1}{2} ke^2$
• What does elastic potential energy represent?

  Energy transferred to an object as it stretches
• What does a graph of force against extension indicate about a spring?

  • Gradient of the line = spring constant
  • Area under the curve = elastic potential energy
• What is the elastic limit in the context of Hooke's law?

  Point where object stops obeying Hooke's law
• What is the limit of proportionality in elasticity?

  Point where Hooke's law no longer applies
