5. When velocity changes, acceleration exists. If an object is changing its velocity, such as its speed or direction, then it is said to be accelerating.
6. The relationship between displacement and acceleration is mediated by velocity, which is also a vector. Velocity is the rate of change of displacement. Displacement is the integral of velocity over time. Acceleration is the rate of change of velocity. Velocity is the integral of acceleration over time.
