Q
How do we add vectors ?
A
Draw a line to scale in the correct direction to represent the first vector
Draw a second line to scale in the correct direction starting from the head of the first vector
Resultant vector is represented in size and direction by the line linking the tail of the first vector to the head of the second

Q
Addition of vectors at 90 degrees
A
Size can be calculated using pythagorous
Direction can be calculated using trig
3
Q
How can we split vectors in horizontal and vertical components ?
A
