Returning Remy's smile, Atlas tried to curb his focus back towards the professor...but it was kind of distracting when there was already a broom in his hands and he had the urge to bat it back and forth like the pendulum on a grandfather clock. Left hand, right hand, left hand, right hand, almost whacking himself right in the nose, left hand. It wasn't distracting enough that he couldn't hear what the professor was saying at least...mostly because it FELT like the man was addressing him directly with this whole crash landing angle because, well, that had been mostly working for him once he had sorted out the timing to jump OFF his broom before it his the pitch. That is during those handful of times he hadn't been thrown off his broom. He hadn't broken any bones OR brooms so...that was already an accomplishment on it's own according to most of the answers regarding the importance of a good landing. Sure, the pitch had charms in place typically so they WOULDN'T break anything but...why bother if no matter what it was going to be 'safe', right?
"Newton," he chimed in after the not-a-crybaby first year Slytherin had mentioned 'some guy'. He had also mentioned him in Ancient Runes so so it was pretty neat to see how muggle concepts were still super pertinent to wizarding society and magical physics. Take THAT, Neo Alliance. "Sir Isaac Newton. Mathematician, physicist, astronomer, theologian, author, and a key figure in the scientific revolution." Just for some context because clearly some people needed to know about 'some guy' so they could stop calling him 'some guy'. Sure, Lisa had elaborated a LITTLE bit more bit...he had started and there was no stopping now."His first law is also known as the Law of Inertia which states that if a body is at rest, it will remain at rest unless it is acted upon by a force, OR a body is moving at a constant speed in a straight line, it will keep moving in a straight line at constant speed unless acted upon by a force. So...yeah. Basically. You, a falling object, are going to keep falling until the ground acts upon you and brings said fall to a sudden stop. So...an object is just going to keep doing what's it's doing...but it's the Second Law you really gotta think about when it comes to falling, because in falling the only force acting on us is gravity pulling us back down at varying accelerations depending on our mass and net force and stuff. The more mass the more inertia. Like...trying to catch a falling bowling ball is going to be harder to stop than a beach ball. But then you gotta ALSO think about the Third Law, which is basically that there is a force exerted on an object, then it it going to exert an equal force back. So like....If I were to try and dismount from my broom only a foot in the air while kind of just coasting parallel to the ground ... it's going to be a pretty safe landing without much risk of injury. No worse than it I were to jump as high as I could and come back down. ...I mean....unless I twist my ankle...which I've done...but anyway...less everything and the force I am putting into the ground with my landing it going to be pretty minor and therefore the ground, er, pushing back at me isn't going to be much. Hence not likely to cause injury unless you're just clumsy. But if you're high up and come ZIPPING back towards the ground and all that...there is gonna be a lot of push back and you're going to get hurt. AND, for the record, capes don't help with this. You might THINK they would because of some additional wind resistance or whatever but...they don't. You just sort of end up with fractured bones when you jump off from somewhere high and then free fall back to the ground." He paused a moment to take a breath because he had NOT been while speaking. "Basically...landings are all about the physics, but Cushioning Charms on the ground cheat that so...if those are in place it is just easier to fall off and let the magic do the work for you."
