Season of Winter, Day 40, 504 AV "These problems are really hard, father!" Jorin whined. His father merely glanced over from his theorems and shook his head. "Don't stop. Keep going," he admonished. There were ten problems. There were always ten problems, each one more difficult than the last. Beads of sweat formed on Jorin's brow as he thought furiously, and his quill hovered above the paper. There are two iron spheres dropped from a tower four hundred hands high. One wieghs eight stone, the other twelve. If the force of a sphere of this nature is the product of their mass and acceleration how much force would they impart when they hit the ground, half a second later? Jorin had no idea where to start. Should he begin with the sphere? But he knew, from experiements his father insisted he carry out, that both spheres would reach the ground at the same time. So wouldn't their acceleration be the same too? Then it was the weight. Jorin glanced forlornly at his answer sheet. It only contained eight answers, of which only five he was relatively certain of. Six was a passing grade. He had no clue how to answer the tenth question. This one was his last hope. So how can he determine acceleration? Jorin dug into the recesses of his memory. There was an equation, surely there was an equation? Something about a certain force that pulled everything to the ground, and how falling objects accelerated at the same rate if dropped and no force pushed it back up. Jorin strained and strained, but he could not remember how the equation worked. His mind was just too out of sorts. And even if he did recall it, he remembered that the equation only gave him the velocity at the END of the fall, so he'd need to take the distance they travelled into account. What was it his father called that? Something about work, and how it ... conserved? Or was conserved? Jorin couldn't remember. A small bell rang, shattering Jorin's concentration. Time was up. Silently, his father walked over, picked up Jorin's answer sheet, sat back down, and eyed it critically, his quill making sweeping movements as it ticked off his answers. One. Two. Three. And then his father's hand stopped. He'd only gotten three questions right. He had failed. Again. |
