  • forces and elasticity
    • a force:
      • A push or pull. The unit of force is the newton 'N'
    • Hookes law
      • When an elastic object is stretched the increased length is called extension. The extension of an elastic object is directly proportional to the force applied to it
        • F is the force in newtons
          • K is the spring constant in newtons per metre
            • E is the extension in metres
  • Spring constant
    • The spring constanT K is different for diffeent objects and materials.
      • Slotted mass: Metal object of specified mass with a slot allowing it to be placed on hangers
  • The spring constanT K is different for diffeent objects and materials.
    • Slotted mass: Metal object of specified mass with a slot allowing it to be placed on hangers
  • Gradient Another word for 'slope' it shows how steep a line is.
