Understanding Vectors

What are the two main characteristics of a vector?

• Speed and size

• Magnitude and color

• Direction and magnitude

• Direction and speed

How can vectors be represented in writing?

• With a dotted line

• With underlining

• With italics

• With bold letters or an arrow on top

What is the horizontal component of a vector?

• The length of the vector

• The direction of the vector

• The change in the x-direction

• The change in the y-direction

How is the magnitude of a vector calculated?

• By multiplying the components

• Using the Pythagorean theorem

• Using the sine rule

• By adding the components

What does a negative scalar do to a vector?

• Increases its magnitude

• Decreases its magnitude

• Reverses its direction

• Changes its color

What happens to a vector when multiplied by a positive scalar?

• It remains unchanged

• It decreases in magnitude

• It increases in magnitude

• It changes direction

How are vectors added graphically?

• By aligning them head to head

• By aligning them side by side

• By aligning them tail to tail

• By aligning them tip to tail

What is the result of adding two vectors?

• A new vector with the same magnitude

• A new vector with the same direction

• A resultant vector

• A scalar value

In vector addition, what is the resultant vector?

• The vector that represents the sum of two vectors

• The vector with the smallest magnitude

• The vector that represents the difference of two vectors

• The vector with the largest magnitude

What is the significance of the parallelogram in vector addition?

• It helps in determining the direction

• It helps in calculating the area

• It helps in visualizing the resultant vector

• It helps in finding the midpoint
