Hookes Laws

• Hookes Law

  This illustrates the relationship between load and extension
• Gravity is defined as force/per unit mass

  $G=$$W/M$
• Weight of an object is measured using a force meter or a spring balance
• The change in length of spring from its initial strength due to weight is called extension
• Hookes law states that the extension of a spring is directly proportional to weight if sports provided that the elastic limit is not exceeded

  $F=$$kx$
• F=force

  k=spring constant

  x=extension
• Spring constant=N/m

  Extension=m

  Spring constant is force/per unit extension
