Oh? They were to clean up now? But the young 'Claw was still at the restroom. Uh-oh. Beezus just decided that she arrange the materials the first year needed neatly on his desk, then she grabbed her own rocket bottle and returned to her own place. Maybe he'll come by in a bit.

One more important thing to discuss?

As instructed, she turned her attention back to the writings on the Board about the Laws of Motion.

Okay. Okay. Okay. The brunette just stayed nodding all the while Professor Burbage gave out explanations and examples after another. There were some she didn't understand, there were also a few she did get. Hmm. Relationship between water and the whole thrusting thing to launch their bottle rocket. That was understandable, and they were going to do the same, yes?

She was so ready to get started with the launching when the woman added more. HUH? The Ravenclaw eyed the statements on the board and started to think. They were to choose one and figure which of the laws relate with it? Frowning, her brain began to work like a machine. First, she chose a statement.

Rockets create thrust by expelling a propellant (water in our case)

She settled for the first choice. "Professor, I believe the first statement fits the second law of motion." Why did she think so? "Well, for one, the statement implies the water fuels the thrust created by the bottle. And if we relate it to the Law of Proportionality, the mass would be the water inside the bottle, and the thrust or the force exerted on the mass upon launch would point out how fast the acceleration would be." Was she making sense here?

Sigh. She wasn't really that good when it came to explaining things.
