• Magnitude is the length of the vector

• Magnitude is the angle of the vector

• Magnitude is the color of the vector

What does the term "direction" describe?

• The speed of an object

• The color of an object

• Where something is located or moving relative to another point or object

• The size of an object

Which direction is represented by the positive vertical axis in the diagram?

• South

• East

• North

• West

What is the definition of distance?

• The shortest path between two points

• The total length an object travels, regardless of its direction

• The time taken to travel from one point to another

• The speed at which an object moves

Based on the diagram, what is the displacement at point A?

• 16 meters

• 8 meters
