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:

• 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:

• Emass, mass, mass

Q5:

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

• 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

Q8:
