Masses you will Ordinary objects tend to have masses between a few grams and a few consider in science hundred kilograms. CHAPTER 2 SCIENCE AND MEASUREMENTHow to solve science problems Physics Problem solving means using what you already know to figure outproblems something you want to know. a. Miguel is told that hot objects, like a cup of coffee, cool off when left on the table in a cooler room. What does milli mean 4. It also analyzed reviews to verify trustworthiness. that can be seen independently byAn example of Scientific evidence may include numbers, tables, graphs, words, others if they repeat the same scientific pictures, sound recordings, or other information. : Table 2.1 shows different units commonly used for speed.Table 2.1: Common units for speed Distance Time Speed Abbreviation meters seconds meters per second m/skilometers hours kilometers per hour km/hcentimeters seconds centimeters per second cm/s hours mph miles miles per hour 2.2 DISTANCE, TIME, AND SPEED 35 Mass and volume We naturally assume that an objects mass is proportional to its size. Sample Assignment. The piece of wood shown above has a mass of 20 grams. The scientific Early civilizations thought Earth was covered by a dom method method is a much more dependable way to learn. If distance is in kilometers and time in hours, then speed is in kilometers per hour (km/h). Instead, set things gently on the balance. For example, 20 feet is a value.motion variable Saying a race car, runner, or plane is fast is not enough to accurately describe its speed scientifically. Like this book? Early hypotheses are rarely correct and are often modified as new evidence becomes available. c. ____ 15 minutes from home to school by bus d. ____ 3:15 on Friday afternoon 5. Arrange the following intervals of time from shortest to longest: conversions? Plastic 2,000 2.0 Figure2.9 gives the densities of some common substances in bothunits. Convert 26 decimeters to meters. New. Your mass is constant throughout the universe, but your weight can change, depending on which Figure2.3: A 2.3-kg bag of flour has the planet you are on! You would easily be able to lift the foam boulder even if it were 1meter across. 4. The important thing is to create something that does the job and fits the requirements. Unlike book problems, design problems have many correct solutions limited only by your creativity, ingenuity, skill, and patience (Figure 2.12). List whether the gram (g) or the kilogram (kg) would be is a ____. A theory is continually tested by collecting new and different evidence. Comparing Mass and Weight Mass Weight amount of matter property of measure of the in an object matter force of gravity acting on an stays the same can be measured objects mass unless you lose or gain matter On Earth: changes when 1 kg = 9.8 N = 2.2 lb gravitational force SI unit: kilogram (kg) changes English unit: slug SI unit: newton (N) English unit: pound (lb) 32 Unit 1 Science and Measurement Grams are also convenient for analyzing food. Never drop things onto a balance! Whatever quality of time.

Hours MondayFriday: 9:00AM-5:00PM Saturday & Sunday: 11:00AM-3:00PM Reviewed in the United States on October 8, 2012. Section 1.316. The relationship v = d t relates what you are asked to find to what you are given. that involve measured quantities? (GraphC). A tenth of a gram is a tiny mass, and balances are therefore sensitive (and quite delicate). Breakfast cereal is sold by mass, not volume, because mass is a more fundamental property that only changes if the amount of cereal (matter) changes.
