Understanding Vector Angles

What is the typical range for recording the angle of a vector?

• 0 to 90 degrees

• 0 to 180 degrees

• 0 to 270 degrees

• 0 to 360 degrees

If a vector is described as '30 degrees north of east', what does this mean?

• The vector starts at east and moves 30 degrees north

• The vector starts at west and moves 30 degrees south

• The vector starts at south and moves 30 degrees west

• The vector starts at north and moves 30 degrees east

How can you convert '28 degrees north of west' to another notation?

• 62 degrees east of north

• 62 degrees west of south

• 62 degrees west of north

• 62 degrees south of east

What is the preferred convention in physics for recording vector angles?

• Between the vector and a vertical line

• Between the vector and a horizontal line

• Using only cardinal directions

• Using only degrees

Why is it rare to use vertical lines for recording vector angles?

• Vertical lines are harder to measure

• Horizontal lines are more intuitive

• Vertical lines are not used in physics

• Horizontal lines are less accurate
