Vector Addition - Polygon Method

What scale is used to represent the forces in the graphical method?

• 1 cm : 0.5 N

• 1 cm : 1 N

• 1 cm : 2 N

• 1 N : 1 cm

When using the polygon method to add vectors, how are successive vectors drawn?

• From the same initial point.

• From the tail of the previous vector to the head of the next vector.

• From the head of the previous vector to the tail of the next vector.

• From the head of the previous vector to the head of the next vector.

What is the magnitude and direction of the resultant force (R) when Force A (3.0 N North) and Force B (4.0 N 30° North of East) are added using the polygon method?

• R = 6.0 N 30° North of East

• R = 5.0 N 55° North of East

• R = 6.0 N 55° North of East

• R = 7.0 N 30° North of East
