  • What is Hooke's Law?
    The extension of a spring is directly proportional to the force applied, provided that the limit of proportionality is not exceeded.
  • What is a Force?
    A force is a push or pull that acts on an object due to the interaction with another object. 
  • What is the equation for Hooke's Law
    F = K x E
  • What is the word equation for Hooke's Law?
    Force = Spring Constant x Extension
  • What is Force measured in?
    Newtons(N)
  • What is Spring constant measured in?
    Newtons per metre (N/m)
  • What is extension measured in?
    Metres(M)
  • What is it called when the objects are physically touching?
    Contact force
  • What is it called when objects aren't phsyically touching?
    Non contact force
  • What do you measure when investigating Hooke's Law?
    Extension
  • extension = stretched lengthoriginal length.
  • What is required for the Hooke's Law practical?
    A steel spring, a 100g mass hanger, 12, 100g masses, a retort stand, a boss and clamp, a clamp, a metre rule, an s-hook, a pointer, safety goggles, a slotted base.
  • A Vector has magnitude and direction
  • A Scalar has just magnitude
  • Give 3 examples of contact forces
    Friction, Air resistance, Tension
  • Give 3 examples of non contact forces
    Magnetic Forces, Gravitational forces and electrostatic force
