  Altitude means how high in the air you are. This is generally not how high above the ground you are over, but how high compared to sea level.
  
  Attitude means how the aircraft is in relation to the horizon (or flat ground). It can be pointing up or down (it's "pitch") or it can be banking left or right (it's "roll"), or any combination of those.
  
  So what does exactly u want to know about....?

  If you are talking about satellites in orbit, altitude cannot be altered without changing the orbit velocity. I f you are considering air borne vehicles you can have any velocity at any altitude within operating limits. As kc.r. says come back with more info on what is bothering you.
