Zoomling — Describing Motion Launch Ramp Cliffs
Hi!
I'm Zoomling.
Welcome to Launch Ramp Cliffs!
Will you help me investigate describing motion?
The Grumblies have mixed up our clues.
Let's check the evidence!
Motion describes position changing relative to a reference point.
Direction, distance and time help us compare journeys.
Which cart is faster over the recorded trip?
- A. B
- B. Both have equal average speed
- C. A
The answer is C: A
Our records show Cart A traveling 4 m in 2 s
and Cart B traveling 4 m in 4 s.
A covers the same distance sooner,
so it has the greater average speed.
That clue helps us make sense of this place.
For the same distance, taking less time means a greater average speed.
For the same time, traveling farther means a greater average speed.
What is the same in both records?
- A. Time and distance both
- B. Distance traveled
- C. Time taken
The answer is B: Distance traveled
For the same distance, taking less time means a greater average speed.
For the same time, traveling farther means a greater average speed.
Hmm...
how does that connect to our first clue?
Our records show Cart A traveling 4 m in 2 s
and Cart B traveling 4 m in 4 s.
A covers the same distance sooner,
so it has the greater average speed.
Why use a reference point?
- A. To describe a change in position
- B. To make all motion disappear
- C. To change the object's material
The answer is A: To describe a change in position
Motion describes position changing relative to a reference point.
Direction, distance and time help us compare journeys.
Nice investigating!
