Vectors and 2D Motion: Crash Course Physics #4

What characteristic do vectors have that scalars do not?

• Magnitude

• Direction

• Acceleration

• Speed

How do physicists graph vectors?

• Using only the x-axis

• By drawing an arrow with a specific magnitude and direction

• By using positive and negative signs

• By measuring the length of the hypotenuse

What happens to the vertical component of a vector if you change its horizontal component?

• It increases

• It decreases

• It remains unchanged

• It becomes zero

In unit vector notation, what does 'i' represent?

• The y-axis

• The magnitude

• The z-axis

• The x-axis

How do you add two vectors in unit vector notation?

• By adding their components separately

• By adding their magnitudes

• By adding their directions

• By multiplying their components
