    Cards (32)

    • Scalars have magnitude but no direction
      True
    • Vector quantities require both magnitude and direction
    • What is the magnitude of a vector?
      Its size or extent
    • Steps of the head-to-tail method for vector addition
      1️⃣ Place the tail of the second vector at the head of the first
      2️⃣ Draw a resultant vector from the tail of the first to the head of the last
    • For vector subtraction, the second vector is drawn in the opposite direction

      True
    • Physical quantities that have only magnitude are called scalars
    • What is the defining characteristic of vectors?
      Magnitude and direction
    • Vectors have magnitude but no direction.
      False
    • What is an example of a vector quantity?
      Displacement
    • The path along which a vector acts is its direction
    • Steps in the Head-to-Tail method for vector addition:
      1️⃣ Draw the first vector
      2️⃣ Place the tail of the second vector at the head of the first
      3️⃣ Draw the resultant vector from the tail of the first to the head of the second
    • In the parallelogram method, the diagonal starting from the origin represents the resultant
    • In arrow notation, what does the length of the arrow represent?
      Magnitude
    • Distance is a scalar quantity that measures the total path length covered by an object.

      True
    • How are vectors added in one-dimensional problems?
      Adding components
    • What is the key difference between scalars and vectors?
      Direction
    • What is an example of a scalar quantity?
      Mass
    • What is an example of a vector quantity?
      Force
    • The direction of a vector is often indicated by an angle or compass bearing
    • What does the diagonal in the parallelogram method represent?
      Resultant vector
    • What is the defining characteristic of scalars?
      Magnitude only
    • Scalars have direction.
      False
    • Physical quantities that have both magnitude and direction are called vectors
    • Match the scalar quantities with their examples:
      Mass ↔️ kg
      Time ↔️ seconds
      Temperature ↔️ degrees
    • Velocity is a vector quantity because it has both magnitude and direction.

      True
    • What is the magnitude of a vector expressed in units like meters or Newtons?
      Size or extent
    • What geometric shape is completed in the parallelogram method for vector addition?

    • In vector subtraction, the second vector is drawn in the opposite direction compared to addition.

      True
    • In component notation, a vector is represented by its x and y components.
    • What is the defining characteristic of displacement?
      Change in position
    • Distance measures the total path length covered by an object.
    • When subtracting vectors in one-dimensional problems, you must consider the direction (positive or negative).
