  1. Unit 2Day 9 Physics

  2. Do Now – BOOK! • Start on a NEW page in your lab notebook. We are beginning Unit 2! • Read section 2.1 Displacement (pages 27 – 28) • You will have five minutes to read it. We will then give you 4 minutes to write. At the end of it, you need to know: • The difference between kinematics and dynamics • The mathematical and verbal description of displacement • The difference between positive and negative displacement

  3. Homework • There is a Unit 1 reflection survey on the wiki. Please take it. • ACT HW #2 is due Friday • Set up your data table in your lab notebook for the lab (this will be worthy of a lasalle)

  4. Definitions and Pre-Cursors • Instants and clock readings vs. time elapsed

  5. Definitions and Pre-Cursors • Vectors and Scalars. • In this room is hidden a small treat. The first team to find the small treat will get to keep it. You will have two minutes. • Directions: • Go 4 meters. • Then go 2 meters. • Then turn. Go 5 meters. • Turn. Go 3 meters.

  6. The Tumble Buggy Lab • AKA the lab of things that move like the energizer bunny… • What do you observe? • Underline your observations that are quantifiable. • Please make your dependent variable… • Position (x) • Note: this is NOT displacement nor distance • Please make your independent variable… • Time (t) • Note: this is a clock reading, not an interval/elapsed

  7. The Tumble Buggy Lab • Question: How does the tumble buggy move? • Side question: What does it mean to move with a constant speed? • Materials available: • Stopwatches, tape, tumble buggies, meter sticks, string, computers • Set up your methods in your notebook. How will you test this lab? • Set up your data table.

  8. Lillenthal’s laws • Things NOT to do: • 1- If reproducibility is a problem, conduct only 1 test. • 2- If a straight line plot is required, collect only two data points.
