Motion is the movement of an object. When we set a point of reference, the motion can be observed.

Speed is the measurement of how quickly or slowly an object moves, but we do not know the direction of the motion.

Velocity covers the information for both speed and its direction.

Acceleration reveals the changing rate of the velocity. Since velocity is a vector, acceleration is also a vector.
