Two New Sciences motion and a naturally accelerated vertical motion which produces a parabolic curve. Two motions at right angles can be calculated using the sum of the squares. He shows in detail how to construct the parabolas in various situations and gives tables for altitude and range depending on the projected angle. [274] Air resistance shows itself in two ways: by affecting less dense bodies more and by offering greater resistance to faster bodies. A lead ball will fall slightly faster than an oak ball, but the difference with a stone ball is negligible. However the speed does not go on increasing
Word polygon Word polygon A word polygon is a word puzzle where the solver is presented with a grid or shape with 5 to 9 letters. The goal is to create as many words as possible using each letter no more than once. There are many variations of the rules, e.g., the minimum word length (usually 3 or 4) may vary, and it may be stipulated that specific letters must be included in any word. The objective of the puzzle is to find words which can be made using a given group of letters. Each letter may only be used once in
