Hypotheses, continued ,[object Object],Chapter 1 If heavier objects fell faster than slower ones,would two bricks of different masses tied together fall slower (b) or faster (c) than the heavy brick alone (a)? Because of this contradiction, Galileo hypothesized instead that all objects fall at the same rate, as in (d). Section 1 What Is Physics?

Sample Problem ,[object Object],[object Object],Section 2 Measurements in Experiments Chapter 1 Given: mass = 2.0 fg Unknown: mass = ? g mass = ? kg

Sample Problem, continued Section 2 Measurements in Experiments Chapter 1 Build conversion factors from the relationships given in Table 3 of the textbook. Two possibilities are: Only the first one will cancel the units of femtograms to give units of grams.

Sample Problem, continued Section 2 Measurements in Experiments Chapter 1 Take the previous answer, and use a similar process to cancel the units of grams to give units of kilograms.

Data from Dropped-Ball Experiment Chapter 1 Section 3 The Language of Physics A clear trend can be seen in the data. The more time that passes after each ball is dropped, the farther the ball falls.

Graph from Dropped-Ball Experiment Chapter 1 Section 3 The Language of Physics One method for analyzing the data is to construct a graph of the distance the balls have fallen versus the elapsed time since they were released. The shape of the graph provides information about the relationship between time and distance.

Extended Response ,[object Object],Standardized Test Prep Chapter 1 Sample answer: Because the type of fertilizer is the variable being tested, all other factors should be controlled, including the type of vegetable, the amount of water, and the amount of sunshine. A fifth row with no fertilizer could be used as the control group. Results could be measured by size, quantity, appearance, and taste.
