After brushing the last wrinkle in your clothes off, caused by the meteoric collapse of your mom's unaware butt, you began to get right back on track with the lesson. You looked out and saw the smiling faces of both Stacy and Shannon, taking a moment to appreciate how much they cared about your passion of teaching. Shaking the daydream out of your head you began to speak once again,
"Okay, well I would say that as unorthodox of a method that the past event was it actually served to explain Newton's first law incredibly well! Do you understand it better now, Stacy?"
"Yeah! It actually made it all click in my head perfectly!" She responded. You couldn't help but grin further at your success at getting through to your sister.
"Alright then let's move onto Newton's second law! This one can be summed up by a neat little equation, F=ma. Or in real words, force equals mass times acceleration. This means that the more mass that something has, the more force will be required to accelerate it!" You concluded your sentence, assuming that this was fairly straightforward stuff, but by the puzzled look on Stacy's face you could tell that you lost her. It astounded you how smart Stacy could be in certain realms yet decently reminiscent of your mother at other times. You knew you had to demonstrate to her this law in action so you sighed before turning to your mom, seated in her ridiculous schoolgirl costume.
"Okay, mom, can I have your assistance once again to show off this concept?" You said, hoping that getting your mother involved would be worth the almost guaranteed pain you were going to suffer.
"Sure!" Shannon responded, practically leaping up from her chair and sending her clearly visible assets bouncing.
"If you would be so kind could you put your foot up on the table next to me?" You asked your mom and she immediately beamed a radiant smile. In her mind she was using her modeling skills to help you with your tutoring and couldn't have felt any happier. Taking a step towards the table, she then lifted her massive right foot and hovered it over the tabletop, before bringing it down carelessly.
You, meanwhile, watched as Shannon's foot plummeted straight for your position. With some flight or fight miracle on your behalf you managed to tumble just out of the way as her slightly dirty sole slapped where you just were. You stood up and brushed yourself off again then began to speak to Stacy once again.
"Okay well look at it like this. Mom's foot has exponentially more mass than my body does." Approaching Shannon's foot you began to take in the slightly sweaty aroma permeating from it. Shannon stared down at you before giggling slightly and wiggling her toes. She could barely contain her excitement for helping you. You continued, "This means it will take exponentially more force from me to move her foot!" You reach out and reluctantly press both hands into the barely damp skin of her foot and try to push with all of your might. Just as you expect, you don't even budge her a millimeter. After a moment you stop your efforts and reclaim your breath before addressing Stacy once more.
"As you can see, I could not apply nearly enough force to cause something with as much mass as mom's foot to accelerate. Uhh, no offense, mom. I'm not saying you are heavy or anything, just speaking scientifically." You direct the latter two sentences upward, just realizing that it might not be the nicest thing in the world to refer to your mother as exponentially more massive than you, no matter how true it is. Thankfully, Shannon laughed and smiled at your little apology.
"Of course not, Sammy. I understand what you're saying" She said down to you before adding on, "and after all compared to you, you're right! My feet are kind of massive, I mean you would have a tough time wrestling one of my little toes!" Once again Shannon managed to belittle your stature completely unintentionally, but you shook off the comment before continuing your lesson.
"On the flip side, I possess significantly less mass than her foot, and correspondingly it would take much less force to get me accelerating quite quickly! If you would be so kind, mom, would you lift your foot and bump me with it to show Stacy?"
"You mean like a kick?" Shannon responded, clearly confused.
"Similar, but definitely not as hard as a full..." you tried to respond, but as soon as you finished saying the world similar Shannon's voice boomed over yours,
"Okay one kick coming right up!" Shannon said loudly before smiling and swinging her right foot far backwards. You gulped, recognizing that you had effectively just asked for a world of hurt, courtesy of your mom turned assistant. Shannon then swung her foot downward like a pendulum, slamming into your form at breakneck speeds.
Like a gunshot you launched clear across the room, rocketed by the force of Shannon's kick. Your mom's smile turned immediately to a fearful gasp as she realized just how easy you were to accelerate. As you were soaring through the air you got your bearings enough to see right what you were headed for... but what was it?
