Build a Prototype: Phase 1
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
BUILD A PROTOTYPE – PHASE 1: EFFECT OF INCLINED PLANE STEEPNESS ON SPEED• Instructions• Make a table in workbook as instructed• Calculate the speed

PRACTICE• Complete the following Worksheets• “Analyzing Graphs of Motion without Numbers”
• “Acceleration and Speed-Time Graphs”
VOCABULARY REVIEW
• Acceleration – the change in velocity per unit time; a = Δv/Δt; unit: m/s/s
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
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

DESCRIBING MOTION
• Displacement – the difference in position between a final position and an initial position; it depends only on the endpoints, not the path; displacement is a vector quantity, it has magnitude (size) and direction
