  23. What is the alternative to scalar drawing?
    Pythagoras or trigonometry
  24. When asked for the resultant, which two pieces of information should you give in your answer
    The force/magnitude (length of the line) and direction (the angle)
  25. A vector is resolved by which metod (finding x and y values)
    Trigonometry - Cos and Sin mainly
  26. An object is in equilibrium if
    The forces acting in all directions are equal and so the resultant is 0
