You will notice that the surface of the liquid forms a curve rather than a straight line (Figure2.4). The Student Edition is available both as a textbook and as an interactive digital ebook, providing today's digital natives with the resources they need in whatever format they want to use. a. Constant means does not change, so constant speed is speed that does not change. CHAPTER 2 SCIENCE AND MEASUREMENTRelationships between distance, speed, and time Mixing up A common type of question in physics is: How far do you go if youdistance, speed, drive for two hours at a speed of 100 km/h? You know how to get speed from time and distance. In everyday language, we use the word weight but hardly ever use the term mass. The first hypothesis that heatcorrectly explain is a form of energy was made by a German doctor, Julius Mayer, in every bit of 1842, and confirmed by experiments done by James Joule in 1843.

Paraffin wax is also made mostly of carbon atoms, density because it also includes the air but the density is only 0.87 g/cm3 (870 kg/m3). If distance is in kilometers and time in hours, then speed is in kilometers per hour (km/h). Figure 2.4: A hot cup of coffee has Hypotheses A scientific hypothesis must be testable. How much mass would a solid piece of granite have that measures 2.00 cm 2.00 cm 3.00 cm? Figure 2.1: The steps in learningTheories In the process of inquiry, the detective asks lots of questions related to the mystery. Second, there cannot be even a single piece of evidence that contradicts the theory. Sometimes this includes numbers or values. A 2.3-kg bag of flour has the same mass no matter where it is in the universe. How many hours will it take the train to travel 600 kilometers? If the italicized word is used correctly, answer correct. If the italicized word is not used correctly, rewrite the statement with the correct word. 1. Describe the relationship between a hypothesis, a theory, and a a less expensive way to make natural law. We now know divided by the same time (1 hour).

This is not a scientific hypothesis because there is no way to test it. The depth of a submarine is a variable speed are variables.that describes how far a submarine is below the surface (Figure 2.6). 95 km/h is the same speed as 59 mph, which is slower than 75 mph. When someone determines the amount of something using a in each case? construction material for decks, docks, and other outdoor projects. Answer: 12 hours Figure 2.9: Using a formula.36 UNIT 1 THE PHYSICAL SCIENCES This was not what people believed in Galileos time.Communicating It is important that scientific evidence be clear, with no room for scientific misunderstanding. The same is true in hypothesis - a possible science, except that the word theory is reserved for a single explanation supported by lots of evidence collected over a long period explanation that can be tested by of time. Here are the PowerPoint Presentations & a few Flash files available for most of the chapters: Chapter 1 - Motion. Oranges and grapes are such as from feet to meters. Whether an object floats or sinks is related to the objects density. For instance, it has been believed at times that creatures result, the air is warmed. The out from known facts using detective must deduce what happened in the past logical thinking. The words at rest in physics mean the speed is zero.

If the life force is undetectable, that means no evidence can be collected that would prove whether it exists or not. Make sure your balance is calibrated properly and shows a reading of zero when it is empty.
