Mechanics

1. Vectors, Forces and Friction

· Vectors have magnitude and direction

· To find the resultant force, line up all the forces tip to tail and connect them up

· Use the sine / cosine rules and rules about angles and parallel lines

· Remember for bearings go clockwise

· Unit Vectors

o Vector of magnitude 1

o Make components of the vector: i and j

o X direction: i

o Y direction: j
