Vectors and Projectiles Quiz

What is the convention used to describe the direction of a vector that is not aligned with the compass points?

• Counterclockwise from north

• Counterclockwise from east

• Clockwise from east

• Clockwise from north

Which of the following is true about vectors and scalars?

• Vectors have neither magnitude nor direction

• Only scalars have magnitude and direction

• Both have magnitude but only vectors have direction

• Both have direction but only vectors have magnitude

How is the magnitude of a vector represented in a diagram?

• By the length of the arrow

• By the direction of the arrow

• By the color of the arrow

• By the width of the arrow

What tools are necessary to determine the magnitude and direction of a vector on a scaled diagram?

• A protractor and a compass

• A ruler and a protractor

• A compass and a ruler

• A calculator and a ruler
