Zingling — Energy of Motion Kinetic Coaster
Hi!
I'm Zingling.
Welcome to Kinetic Coaster!
Will you help me investigate energy of motion?
The Grumblies have mixed up our clues.
Let's check the evidence!
Moving objects have energy of motion.
For the same object, greater speed means more energy of motion.
Which same-cart trial has more motion energy?
- A. The slower one
- B. Both at every possible speed
- C. The faster one
The answer is C: The faster one
Moving objects have energy of motion.
For the same object, greater speed means more energy of motion.
That clue helps us make sense of this place.
Collisions can transfer energy to other objects
and change their motion or shape.
Compare the same object to isolate the effect of speed.
What is kept the same in the comparison?
- A. Speed and dent size
- B. Cart and barrier
- C. Speed
The answer is B: Cart and barrier
Our model sends the same cart into the same soft
barrier at two speeds.
The faster trial makes a larger dent.
That result supports a speed-related difference under these conditions.
Hmm...
how does that connect to our first clue?
Our model sends the same cart into the same soft
barrier at two speeds.
The faster trial makes a larger dent.
That result supports a speed-related difference under these conditions.
What evidence differs in the record?
- A. Dent size
- B. The cart's label only
- C. Only the chart title
The answer is A: Dent size
Our model sends the same cart into the same soft
barrier at two speeds.
The faster trial makes a larger dent.
That result supports a speed-related difference under these conditions.
Nice investigating!
You've been following the evidence.
