1.1 Scalars and Vectors

• What is a scalar quantity defined by?

  Magnitude only
• Scalar quantities have both magnitude and direction.

  False
• Match the type of quantity with an example:

  Scalar ↔️ Mass

  Vector ↔️ Force
• The direction of the arrow in a vector's graphical representation indicates its numerical value.

  False
• Temperature is an example of a scalar quantity
• Name two examples of scalar quantities.

  Mass and time
• Vector quantities are physical quantities that have both magnitude and direction
• What is the defining characteristic of scalar quantities?

  Magnitude only
• Vector quantities have both magnitude and direction
• Scalar quantities are described solely by their magnitude
• What does the length of an arrow represent in a vector's graphical representation?

  Magnitude
• What are examples of vector quantities?

  Displacement, velocity, force, acceleration
• Scalar quantities have magnitude but no direction
• In a graphical representation of a vector, the length of the arrow represents its magnitude.


  True
• Give an example of a vector quantity.

  Velocity
• A displacement of 5 meters north can be represented graphically as an arrow pointing north.


  True
• Scalar quantities can be fully described by a single number, while vector quantities require both magnitude and direction.


  True
• Vector quantities include displacement, velocity, force, and acceleration
• What is the defining characteristic of vector quantities?

  Magnitude and direction
• What are scalar quantities fully represented by?

  A single number
• Match the quantity type with its description:

  Scalar ↔️ Magnitude only

  Vector ↔️ Magnitude and direction
