DOES THE ELECTRON HAVE A CONSTANT VELOCITY?EXPLAIN?
If you are considering the electron as a particle, it is easier to understand it does not circle with a constant speed.

Orbitals are not totally round, more like elliptic. The electron is attracted towards the nucleus with a Coulomb force inversely proportional to the distance at second degree. There is a centripetal force too, which affects the electron in a tangential direction, keeping it at the orbital. Also, there are numerous different quantum physical forces also. Most of these forces depend on the location of the electron, better said, the distance from the nucleus, and because it is not a round orbital, the distance is not constant. Therefore, higher speed might occur at different locations.
