Open Ended

Explain the steps you would take to solve a problem involving the calculation of speed, given distance and time.

Multiple Choice

Why might the distance you drive to a location be greater than the straight-line distance between your starting point and your destination?

• Roads are not straight and may have curves or detours

• You made a mistake in calculation

• The straight-line distance is always longer

• The car moves slower on straight roads

Open Ended

How does the difference between the straight-line distance and the actual distance traveled relate to the concepts of displacement and distance?

Multiple Choice

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

• Distance is the total path traveled, while displacement is the straight-line change in position and direction.

• Distance is always less than displacement.

• Displacement is the total path traveled, while distance is the straight-line change in position.

• Distance and displacement are always equal.

Fill in the Blank

What is the symbol used for displacement and what does it represent?

Multiple Choice

Why is the x-axis commonly used to represent position in displacement problems?

• Because it allows us to show direction and magnitude of movement clearly.

• Because it is always positive.

• Because displacement only occurs in one direction.

• Because it is easier to draw than other axes.

Fill in the Blank

Fill in the blank: The formula for calculating displacement is Δx = ___ - ___

Multiple Select

Which of the following are true about displacement?

• It can be negative or positive depending on direction.

• It is always equal to the distance traveled.

• It is measured in meters (m) in the SI system.

• It depends on the initial and final positions, not the path taken.
