      Question

      What is the relationship between acceleration and

      velocity?
      A Acceleration is the rate of change of velocity Correct Answer Incorrect Answer
      B Velocity is the rate of change of acceleration Correct Answer Incorrect Answer
      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 = Ξ”v/Ξ”t).
      - If velocity changes (increases/decreases or changes direction), acceleration occurs.
