Physics Kinematics: Motion in a Straight Line - Scalars and Vectors

What is the main difference between scalar and vector quantities?

• Vectors have direction, scalars do not.

• Vectors have units, scalars do not.

• Scalars have direction, vectors do not.

• Scalars have units, vectors do not.

Which of the following is an example of a scalar quantity?

• 5 meters east

• 2 meganewtons west

• 10 minutes

• 3 kilometers north

Why is the number of passengers on a train considered a scalar quantity?

• It is a vector.

• It is always changing.

• It has a magnitude and units.

• It includes a direction.

Which of the following is a vector quantity?

• Pi

• 3 kilometers east

• 10 seconds

• 163 passengers

In the scenario with Vector Man, what was the direction of the force he applied to the train?

• South

• North

• West

• East

How are vectors typically represented in diagrams?

• With circles

• With squares

• With numbers only

• With arrows indicating direction

What is the importance of including units when writing scalar and vector quantities?

• Units make the measurement meaningful.

• Units are not important.

• Units help in identifying the type of quantity.

• Units are only needed for vectors.

Which notation is used to represent vectors in equations?

• Lowercase letters

• Boldface

• Right-pointing arrow on top

• Squiggle underneath

What should you include when calculating a vector quantity?

• Magnitude only

• Magnitude and units

• Magnitude, units, and direction

• Direction only

How can you determine if a quantity is a vector?

• By adding a direction and seeing if it makes sense

• By checking if it has a magnitude

• By checking if it is a number

• By checking if it has units
