Science Skills Chapter 2 Units of density Material (kg/m3) (g/cm3)FOR SAMPLE ONLY - NOT FOR CLASSROOM USE Density in units of Your laboratory investigations will typically use density in units of grams Platinum 21,500 21.5 grams per milliliter per milliliter (g/mL). solder takes up 52.6 mL. Many problems involving speed, distance, and time ask you to calculate something using formulas. Each theory is continually tested against the results of observations and experiments. Calculate the average speed (in km/h) of a car that travels taken you? A local power plant begins with a quantity of coal. design cycle to turn your idea into a practical solution.element energy force 3. We and 59 mph are really the same because factors flip the conversion factor upside down so the units of km cancel out! The is a measurement system used for everyday Section 1.1 measurements in the United States. For example, the balance in Figure2.2 shows the mass of six steel nuts to be 96.2 grams. Foam is light and airy, or low density, and even a large volume of foam has very little mass. That makes the sketches repeatable. If 1,000 dollar bills have a mass of one kilogram, 1 dollar bill 8. That means the sketches are objective. How many dimensions are needed to describe the location of a stationary baseball?9. Try it for yourself: Can you think of something with a mass of 1 kilogram? 4. How can two experimental results be considered the same if b. Mass is Although mass and weight are related quantities, always remember the fundamental difference. Does what other people think qualify as scientific evidence?
