Below are sample questions representative of the exercises included on this worksheet and related 3.12 Safety and Tools for Measuring Motion skill assessments:

Problem 1Difficulty: Mastery

Grace sets a 2 m course. She uses a ruler and moves it end-to-end, but she leaves gaps between ruler placements.

How will that affect her distance data?

AThe distance will be too big because rulers add extra.

BTime will get faster.

CIt will not change anything.

DThe distance will be too small because the gaps were not counted.

Solution & Explanation:If you skip parts of the path, you miss distance, so the measurement is too small.

Problem 2Difficulty: Mastery

Sam's group wants to share results. Another group used inches by mistake.

What should both groups do so the class can compare motion data fairly?

AKeep different units because it's fine.

BChange the toys so results match.

CUse the same unit (like centimeters) and re-measure if needed.

DOnly compare the fastest times and ignore distance.

Solution & Explanation:Fair comparisons need the same unit for distance; otherwise, the numbers don't match.

Problem 3Difficulty: Mastery

Leila is comparing two toys. Toy A goes 120 cm in 6 s. Toy B goes 90 cm in 4 s.

Which tools were used to collect the needed data for this comparison?

Aa thermometer and a scale

Ba distance tool (ruler/tape) and a stopwatch

Ca compass and a protractor

Da stopwatch only

Solution & Explanation:You need distance (cm) and time (s). That means a ruler/tape and a stopwatch.
