Unformatted text preview: higher speed (magnitude) Constantly decreasing slope (convex) in position means constant SLOWING of speed (slope) Position > speed > acceleration. Scalar = Speed, Vector = Velocity o Other Scalar: Mass, quantities… stuff that doesn’t need direction • Vectors o Addition of vectors (summing after you draw the directions) o Subtraction of vectors. o Other shit • Acceleration = rate of change in velocity over time o Forces associated with acceleration. o Instantaneous acceleration calculated by taking short time interval where acceleration doesn’t change much. o Direction of acceleration Deceleration vs. acceleration. o When velocity is constant, acceleration is 0. The reason that coke doesn’t spill all over you when you pour it in a cup on a train going 100 miles an hour 16/01/2008 13:06:00 16/01/2008 13:06:00...
