  1. Physics A First Course Forces and Motion Chapter 1

  2. Forces and MotionDescribing the Physical Universe • 1.1 What is Physics? • 1.2 Distance and Time • 1.3 Speed

  3. natural law experiment analysis mass system variable macroscopic scientific method independent variable dependent variable hypothesis controlled variable experimental variable model Explain what makes up the universe. Describe how the scientific method is used. Explain the effects of energy on a system. Chapter 1.1 Objectives and Vocabulary

  4. Key Question: How is motion described and measured in Physics? 1A Investigation: Time, Distance, and Speed *Students read text section 1.2 AFTER Investigation 1A

  5. 1A Investigation Topics • Learn uses and functions of CPO Timer and photogates. • Set car to travel at constant speed. • Measure time intervals. • Calculate speed from time interval measurements. • Graph position vs. timer for car traveling down track.

  6. distance length English system metric system time interval second Express distance measurements in both English and metric units. Measure time intervals in mixed units. Distinguish between independent and dependent variables. Construct graphs. Convert between different units of time. Chapter 1.2 Objectives and Vocabulary

  7. Key Questions: Why do things change? Why do things change by only a certain amount? 1B Investigation: Systems, Energy and Change *Students read text section 1.3 AFTER Investigation 1B

  8. 1B Investigation Topics • Measure time intervals. • Calculate speed from time interval measurements. • Identify variables in an experiment. • Identify dependent and independent variables. • Control variables in an experiment. • Compare speeds and energy of car.

  9. speed constant speed Define speed. Express an object's speed using various units. Calculate speed, distance or time given two of the three quantities. List the steps for solving physics problems. Chapter 1.3 Objectives and Vocabulary
