Lesson Worksheet: Scalars and Vectors Science

In this worksheet, we will practice defining physical quantities as scalars or vectors depending on whether they have a direction.

Q1:

What must a vector quantity have that a scalar quantity must also have?

  • AA magnitude
  • BA direction

Q2:

What must a vector quantity have that a scalar quantity cannot have?

  • AA direction
  • BA magnitude

Q3:

Fill in the blanks: A displacement is a distance in a particular direction. Displacement is the quantity of change of .

  • Ascalar, position
  • Bvector, speed
  • Cscalar, speed
  • Dvector, position

Q4:

Fill in the blanks: The of an object has a direction that points from the center of of the object to the center of of Earth.

  • Aweight, mass, mass
  • Bweight, weight, weight
  • Cmass, gravity, mass
  • Dmass, gravity, gravity
  • Emass, mass, mass

Q5:

Fill in the blank: A velocity is a speed in a particular direction. Velocity is the change of with time.

  • Adistance
  • Bdisplacement
  • Cspeed

Q6:

Which of the following best states what a physical quantity is?

  • AA physical quantity is a measurement of something.
  • BA physical quantity is something that can be measured.

Q7:

Is force a vector or a scalar quantity?

  • AVector
  • BScalar
