Vector Components on a Grid Quiz

What are vector components in relation to a grid?

• They are the length of a vector.

• They are the projections of a vector onto the x and y axes.

• They are the color of a vector.

• They are the angles of a vector.

How do you determine the x component of a vector on a grid?

• By counting how far the vector moves up or down.

• By measuring the angle of the vector.

• By measuring the length of the vector.

• By counting how far the vector moves to the right or left.

If a vector moves 3 boxes to the right, what is its x component?

• -3

• Cannot be determined

• 0

• 3

What does a negative y component indicate about a vector's movement?

• The vector moves to the left.

• The vector moves to the right.

• The vector moves downwards.

• The vector moves upwards.

How do you find the components of a vector drawn on graph paper?

• By measuring the angle of the vector.

• By counting the boxes from the tail to the head.

• By measuring the length of the vector.

• By using a protractor.

What is the x component if a vector moves 2 boxes to the left?

• Cannot be determined

• 0

• -2

• 2

How do you draw a vector from given components on a grid?

• By using a compass.

• By measuring the length of the vector.

• By counting boxes based on the components.

• By drawing a line at a specific angle.

What is the y component if a vector moves 1 box up?

• -1

• 0

• 1

• Cannot be determined

What tool can help practice vector components on a grid?

• The PHET vector addition simulation

• A protractor

• A ruler

• A calculator

What does the PHET program allow you to do with vectors?

• Measure their angles

• Change their color

• Adjust their size and see component changes

• Calculate their length
