Zoomling — Predicting & Testing Motion Runaway Engine Vault

Hi!

I'm Zoomling.

Welcome to Runaway Engine Vault!

Will you help me investigate predicting & testing motion?

The Grumblies have mixed up our clues.

Let's check the evidence!

Motion predictions improve when they use repeated test evidence.

Compare relevant conditions and recognize that a model has limits.

Which design meets the stopping goal in these trials?

  • A. Neither despite repeated stops
  • B. The textured zone
  • C. The smooth zone

The answer is B: The textured zone

Our three trials show a textured stopping zone stopping the

cart within the marked area each time;

a smooth zone lets it pass.

The textured design fits the recorded goal,

while more conditions could need more testing.

That clue helps us make sense of this place.

A stopping design should meet the goal under the tested conditions.

Forces from surfaces or barriers can change the cart's motion.

Why repeat a trial?

  • A. To check the result's consistency
  • B. To replace all observation with a guess
  • C. To avoid recording observations

The answer is A: To check the result's consistency

Our three trials show a textured stopping zone stopping the

cart within the marked area each time;

a smooth zone lets it pass.

The textured design fits the recorded goal,

while more conditions could need more testing.

Hmm...

how does that connect to our first clue?

Our three trials show a textured stopping zone stopping the

cart within the marked area each time;

a smooth zone lets it pass.

The textured design fits the recorded goal,

while more conditions could need more testing.

Which evidence supports the choice?

  • A. The design had the nicest title
  • B. A label promising success
  • C. The cart stopped within the marked area

The answer is C: The cart stopped within the marked area

Our three trials show a textured stopping zone stopping the

cart within the marked area each time;

a smooth zone lets it pass.

The textured design fits the recorded goal,

while more conditions could need more testing.

Nice investigating!

You've been following the evidence.
