TEKS 7.7A - Calculating Average Speed
"Explain and calculate average speed using distance and time measurements from investigations."
Key Formula: Average Speed = Total Distance ÷ Total Time ($S = D / T$)
TEKS 7.7B - Speed vs. Velocity
"Distinguish between speed and velocity in linear motion in terms of distance, displacement, and direction."
Speed = Scalar (Magnitude only).
Velocity = Vector (Speed + Direction).
Distance = Total path length. Displacement = Straight-line distance from start to finish.
