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 superiority effect observer is then asked to name one of the letters from the cued position in that word or string making the test a two-alternative forced choice (2-AFC). For example, for the letter R in the word "card", an observer might be asked to choose between the letter R and T, and will usually be more efficient in doing so than if they are asked to make the same choice with the string of letters such as "cqrd". Each possible completion with the two possible letters in the word condition produce a word. The WSE has since been exhaustively studied in
