5.1.1 Scalar and Vector Quantities

• Distance is an example of a scalar quantity.
• What is a scalar quantity?

  Magnitude but no direction
• What is a vector quantity?

  Magnitude and direction
• Force describes both the strength and direction of a push or pull.


  True
• What is the key characteristic of a scalar quantity?

  Magnitude but no direction
• What is required to fully define a vector quantity?

  Magnitude and direction
• Force indicates both the strength and direction of a push or pull.


  True
• A vector quantity requires both magnitude and direction
• What is the direction of velocity?

  Movement direction
• What does velocity describe in physics?

  Speed and direction
• Give an example of a scalar quantity that measures temperature.

  25°C
• Scalar quantities require direction to be fully defined.

  False
• Time is a scalar quantity measured in units such as hours
• Vector quantities have both magnitude and direction.


  True
• Energy is a scalar quantity measured in units called joules
• What is the direction of force?

  Direction of push/pull
• Scalar quantities require both magnitude and direction.

  False
• Scalar quantities require both magnitude and direction to be fully described.

  False
• Velocity is an example of a vector quantity.
• Match the quantity with its type, magnitude, and direction:

  Velocity ↔️ Vector, Speed, Movement Direction

  Force ↔️ Vector, Strength, Push/Pull Direction

  Displacement ↔️ Vector, Distance, Initial to Final Position

  Acceleration ↔️ Vector, Rate of Change, Change Direction
• Scalar quantities have both magnitude and direction.

  False
• Displacement has a magnitude of distance and a direction from the initial to the final position.
• What is a vector quantity defined as?

  Both magnitude and direction
• Scalar quantities require both magnitude and direction to be fully defined.

  False
• The magnitude of force is its strength
• Scalar quantities have both magnitude and direction.

  False
• The magnitude of speed is measured in units such as km/h
• What is an example of a scalar quantity that measures mass?

  50 kg
• Name an example of a vector quantity that measures displacement.

  Distance
• What is the direction of a scalar quantity?

  None
• Scalar quantities have magnitude but no direction.


  True
• Velocity describes how fast an object is moving and in which direction
• Give an example of a scalar quantity that measures time.

  Time
• The key difference between scalar and vector quantities is that scalar quantities only have magnitude.

  True
• A vector quantity requires both magnitude and direction
