Eddie's eyes stare confusingly at the physics book he's holding. Him and Buck planned on helping Chris for an upcoming test, but neither of them considered the fact that both couldn't understand a word that was written there.
"Okay so... Uniform motion occurs when an object's velocity does not change; its speed remains constant from beginning to end. In an environment where air resistance is minimal, When an object is thrown horizontally, it undergoes uniform motion." Eddie starts, not really understanding what he's reading, but continues anyway, "Uniformly varied motion occurs when an object undergoes a change in its speed along its path; it can gain or lose speed. Its speed changes proportionally every second. In an environment without air resistance, an object thrown vertically undergoes uniformly accelerated motion, since its acceleration will be greater."
"Okay.." Chris answers, noting the information in his notebook.
"Now, When two objects are dropped from the same height in a vacuum, they fall at the same time, for example, a feather and a bowling ball. The force of gravity acts on both in the same way; disregarding air resistance, they will fall solely due to the force of gravity acting on them." Buck starts, "And also, when an object is thrown upwards, At its highest point, its speed will be 0, as the object travels to its highest point, it decelerates, slowing down until its velocity reaches 0. When it reaches its highest point, for an instant its speed will be 0, but the force of gravity will continue to act on it; that is, at the highest point the object can reach, Its speed is zero, but acceleration continues to act on it, and it will instantly begin to fall."
"For gravity, it doesn't matter if an object is being thrown vertically or horizontally; it will continue to act on both in the same way, that is, if in an environment where If air resistance is negligible, and two objects are thrown, one horizontally and one vertically, they will both fall together, since gravity acts on both in the same way. The objects fall independently of each other." Eddie adds to Buck's speech.
"Okay! I think I understood... Thanks dad! Thank you Buck." Chris smiles as he finishes his notes.
"You're welcome, buddy." Buck pats his head and sits again on Eddie's couch, next to him.
"Did you understand anything that you read?" Eddie asks, "Of course I didn't, I don't even understand how the kid does" Buck leans on Eddie as he speaks, "but he sure is a little genius."
"Yeah, he surely is."
