4 By the end of today, IWBAT - Review for the Unit 2 exam Why it matters in LIFE: Part of being a functional human being is being able to understand what s happening in the world around you! Why it matters in THIS CLASS: Our Goal = 80% Mastering today s lesson (focused participation, asking questions, etc) is the first brick that will help us reach our goal for this unit, and eventually for the year

7 UNIT 1 KINEMATICS
8 DISTANCE, d units (meters, m) The total additive distance an object travels.
9 DISPLACEMENT, Δd units (meters, m) The distance between an object s final position and initial position. Δd = d f - d i
10 VELOCITY, v units (meters/second, m/s) The change in an object s position over time. An object s speed and direction. v = Δd Δt
11 ACCELERATION, a units (meters/second/second, m/s 2 ) The change in an object s velocity over time. Speeding up, slowing down, or staying the same. a = Δv Δt
12 VECTOR An item with both MAGNITUDE & DIRECTION 30 degrees
13 MAGNITUDE units (same as what you are measuring, ie d units m) How much! Ex: a force with a magnitude of 6N is the same as saying a force of 6N.
14 THETA, θ units (degrees ) And object s direction as an angle.

16 UNIT 1 MOTION GRAPHS
17 POSITION-TIME GRAPHS Position is found on the y-axis Distance is found by adding up the position lengths of each segment = 8 Displacement is found by final position initial position 2-0 = 2 Velocity is found by the slope v = m = -3/4 2 Acceleration is found by 0 the shape of the slope Straight: a = Curved: a 0 a=0 4
18 Position (m) POSITION-TIME GRAPH PRACTICE 1. Position at time t = 8s 2. Distance traveled from t = 2s to t =7s 3. Displacement from t = 2s to t = 7s 4. Velocity at time t = 9.5s 5. Acceleration at t = 1s 6. Total distance and displacement over the entire 11s. 1. 3m 2. 2m + 3m = 5m 3. 3m (-2m) = 5m 4. v = m = -3m/s Time (s) 5. a = 0m/s 2 6. d = = 11m Δd = -3m (-2m) = -1m
19 VELOCITY-TIME GRAPHS Distance is found by adding up the areas under the curve as positives Displacement is found by adding the areas above the x-axis and subtracting those below Velocity is found on the y-axis Acceleration is found by the slope a = 3/2 2 3
20 VELOCITY-TIME GRAPHS PRACTICE 1. Distance traveled from t = 2s to t =4s 3. Displacement from t = 2s to t = 4s 4. Velocity at time t = 3.5s 5. Acceleration at t = 1s 6. Total distance and displacement over the entire 6s. 1. d = 1(10) + ½(1)(10) = 15m 2. Δd = 1(10) + ½(1)(10) = 15m 3. 5m/s 4. a = m = 10/1.5 = 6.67m/s 5. d = ½(1.5)(10) + 1(10) + ½(1)(10) + ½(1)(10) + 1(10) = 37.5m Δd = ½(1.5)(10) + 1(10) + ½(1)(10) - ½(1)(10) - 1(10) = 7.5m
