Adding and Subtracting Vectors

What is the main difference between scalar and vector quantities?

• Scalars have no direction, vectors do not have magnitude
• Scalars have magnitude, vectors have magnitude and direction
• Scalars have magnitude and direction, vectors only have magnitude
• Scalars have direction, vectors have no direction

Can the distance be obtained by adding magnitudes of vectors?

• Yes
• No

What is the first step in adding vectors geometrically?

• Draw the first vector
• Arrange vectors tip to tail
• Draw the resultant vector
• Move a vector

What does the resultant vector represent in the geometric addition of two vectors?

• The magnitude of the first vector
• The magnitude of the second vector
• The sum of the magnitudes of both vectors
• The vector sum of two vectors

How is subtraction related to adding a negative number?

• Subtraction is the same as adding a positive number
• Subtraction is the same as multiplying by a negative number
• Subtraction is the same as adding a negative number
• Subtraction is the same as dividing by a negative number

What is the first step in subtracting vectors geometrically?

• Draw the vector being subtracted
• Multiply the vector being subtracted by -1
• Draw the resultant vector
• Start by taking the negative of the first vector

Can the magnitude and direction of a vector change when it is moved?

• Yes
• No

What is the result of adding two vectors that are in opposite directions?

• The sum is zero
• The sum is the magnitude of the larger vector minus the magnitude of the smaller vector
• The sum is the magnitude of the smaller vector minus the magnitude of the larger vector
• The sum is the sum of the magnitudes of both vectors

What is the result of adding two vectors that are perpendicular to each other?

• The sum is zero
• The sum is the magnitude of the larger vector minus the magnitude of the smaller vector
• The sum is the magnitude of the smaller vector minus the magnitude of the larger vector
• The sum is the vector sum of two vectors

What is the result of subtracting two vectors that are in opposite directions?

• The difference is zero
• The difference is the magnitude of the larger vector minus the magnitude of the smaller vector
• The difference is the magnitude of the smaller vector minus the magnitude of the larger vector
• The difference is the vector difference of two vectors
