    • Weight
      The gravitational force acting on an object through its centre of mass.
    • Friction
      The force that arises when two surfaces rub against each other.
    • Drag
      The resistive force on an object travelling through a fluid; the same as friction. For most objects, drag is deirectly proportional to speed squared.
    • Tension
      The force within a streched cable or rope.
    • Upthrust
      An upward buoyancy force acting on an object when it is in a fluid.
    • Normal contact force
      A force arising when one object rests against another object.
    • Centre of gravity
      An imaginary point at which the entire weight of an object appears to act.
    • Centre of mass
      A point through which any externally applied force produces straight line motion but no rotation.
