What is the difference between acceleration, speed and velocity?

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.(Amount of increase or decrease in velocity). Also, speed is a scalar quantity but velocity and acceleration are vector quantities.
