Lesson 1.1 Interactive Practice (Classwork)

Which of the following is a scalar quantity?

• Displacement

• Distance

• Velocity

• Acceleration

Which of the following best describes the difference between distance and displacement?

• Distance is a vector, displacement is a scalar.

• Distance is the shortest path, displacement is the total path.

• Distance is the total path length, displacement is the shortest straight-line path.

• Distance and displacement are always equal.

If a car travels 100 m east and then 100 m west, what is its displacement?

• 0 m
