Vectors

• Scalar has only a magnitude, no direction, e.g length mass speed

  Vector has a magnitude and a direction, e.g Velocity displacement momentum
• For parallel vectors we either add them or take them away from each other
• Perpendicular vectors:

  We line them up so that they are tip to tail and then us Pythagoras
• Resolving vectors:

  Split them up into horizontal and vertical components and then use trigonometry to solve
• For non purpendicular vectors use cosine rule/ sine rule
