MOTION
  1. COMPARED TO
    1. Reference point (Relative motion)
      1. Used for comparison
        1. Determines if something is in motion
        2. Two kinds
          1. Moving
            1. Might trick you
              1. Such as other car moving
              2. Stationary
                1. Preferably
                  1. Such as tree or pole
            2. MEASURED IN
              1. Internationl system of Units (SI)
                1. Used by scientists all over the world
                  1. Describes all quantities
                    1. Sush as length, mass time, current, temperature, intensity and amount of substance
                    2. "System Internationale" in French
                  2. DESCRIBED BY
                    1. Acceleration
                      1. Increase in speed
                        1. Decrease in speed
                          1. Change in directiom
                            1. Final speed minus initial speed over time
                              1. Time always squared
                                1. Rate at which velocity changes
                                2. Graphs to analyse acceleration
                                  1. Speed versus Time
                                    1. Distance versus time
                                3. HAPPENS WHEN
                                  1. Change in Velocity
                                    1. Speed
                                      1. Distance over time
                                        1. Distance versus time graph
                                          1. Slope
                                            1. Steepness tells you if moving slower or faster
                                              1. Straight line = constant speed
                                                1. Represents rate of change d/t (speed)
                                                  1. Calculate by dividing rise over run
                                              2. Two Kinds
                                                1. Instantaneous
                                                  1. Measured by speed graph
                                                  2. Average speed
                                                    1. Total distance over total time
                                                2. Direction
                                                  1. Very crucial in some casses
