This block introduces the concepts of displacement, velocity, and acceleration. A key shift in 9th grade is the use of to show that both magnitude and direction matter. Average Velocity : s⃗modified s with right arrow above is displacement (m) and is time (s). Acceleration : Measures the rate of change of velocity; v0⃗modified v sub 0 with right arrow above is initial velocity and v⃗modified v with right arrow above is final velocity. Velocity for Uniformly Accelerated Motion : Displacement (Kinematic Equation) : Kinematics: Describing Motion (Para 1–9) Used to find
