Scalar product of vectors

What is the scalar product of two parallel vectors?

• 1

If the dot product of two vectors is equal to zero, then what do we know about the two vectors?

• They are parallel.

• They are perpendicular.

• They are unit vectors.

• They are both zero vectors.

What is magnitude?

• The direction that describes a quantity.
• A numerical value
• A unit of force

Which statement describes a vector?

• It has magnitude but no direction
• It has direction but no magnitude
• It has both direction and magnitude
• It has constant magnitude but no
   direction

What is equal vectors?

• If two parallel vectors have the same values

• If they are in opposite directions

• If they have same magnitude and anti-parallel

What is anti-parallel vectors?

• If two parallel vectors have the same values

• If they are in opposite directions

• If they have same magnitude and anti-parallel

The _______ of two or more vectors is the sum of the vectors.

• components
• scalar
• resultant
• magnitude

• A and B are colinear

• A and B are parallel

• A and B are perpendicular

• None of the above 

If the dot product of two vectors is equal to zero, then what do we know about the two vectors?

• They are parallel.

• They are orthogonal.

• They are neither.

How do you know if two vectors are orthogonal?

• Their sum is 0.
• The dot product is 1.
• The angle between them is 0°.
• The dot product is 0.
