    C Acceleration and velocity are unrelated Correct Answer Incorrect Answer
    D Acceleration is the speed of an object Correct Answer Incorrect Answer

    Solution

    - Velocity = Rate of change of position (speed + direction).
    - Acceleration = Rate of change of velocity over time (a = Δv/Δt).
    - If velocity changes (increases/decreases or changes direction), acceleration occurs.
