1. Build a Prototype: Phase 1

2. BUILD A PROTOTYPE – PHASE 1: EFFECT OF INCLINED PLANE STEEPNESS ON SPEED Instructions Obtain switch, plane, steel ball, and half meter sticks Set up switch as instructed by instructor Make a table in workbook as instructed Heights: 2cm, 4cm, 6cm, 8cm, and 10 cm height Ramp: 20cm Time of descent

3. BUILD A PROTOTYPE – PHASE 1: EFFECT OF INCLINED PLANE STEEPNESS ON SPEED Instructions Make a table in workbook as instructed Calculate the speed Graph results

4. BUILD A PROTOTYPE – PHASE 1 Instructions Distance v. Time Graph d t

7. PRACTICE Complete the following Worksheets “Analyzing Graphs of Motion without Numbers” “Acceleration and Speed-Time Graphs”

8. VOCABULARY REVIEW Acceleration – the change in velocity per unit time; a = Δv/Δt; unit: m/s/s

9. VOCABULARY REVIEW Speed – the distance traveled divided by the time elapsed; speed is a scalar quantity, it has no direction v = Δd/Δt; unit: m/s Velocity – the speed in a given direction; displacement divided by the time interval; v = Δd/Δt; unit: m/s

10. VECTOR VS. SCALAR Vector – a quantity that has both magnitude (size/amount) and direction Scalar – a quantity that has magnitude (size/amount) but no direction
